Navigation Manager

Before the Navigation Manager can be used, the Hydra Client process must be configured and running

and the Navigation Manager must have access to Hydra Server, either on the local or a remote machine. If

Hydra Server is running on a remote machine, the local machine and user must be defined in the Hydra

Admin table on the machine running Hydra Server.

Overview

The Navigation Manager is a tool that helps the user with an appropriate online QC and also allows

compiling suitable End of Line Reports. Apart from monitoring raw or processed data, the user is able to

view real time statistical information. There are different display options including graphs, tables, scatter

plots and frequency charts. Data can also be logged to a file as text. Different Tabs and Panes can be set

up to allow grouping of similar data to enhance readability.

It is also possible to save (export) all the settings once the Navigation Manager is configured and also to

import data of a line that has been shot previously to re-generate an End of Line Report, in case it is

required.

Invoke Navigation Manager from the Start Menu/Programs/Triggerfish/Navigation Manager.

Once the Navigation Manager is started the following window will show up:

Toolbars and panes can be selected and setup for the user’s convenience using the “View” menu:

Tools Pane


3/53


Page 3 of 53

For example the “Tools” Pane on the right hand side of the window can be selected or deselected. This

Pane contains “Data Objects” and “Captions”. The “Data Objects” section gives the user a selection of

possible displays within the Navigation Manager, where the “Caption” part holds tools to setup and

design the Cover Page of an End of Line Report.

It is also possible (and it might be a good idea!) to include the “Page Manager” to the window, as shown

in the picture below. Most likely you will have several different Panes or Tabs setup to monitor the dataand perform an online QC. The “Page Manager” can help to organize or edit all the different Tabs or

Panes you have set up in the Navigation Manager. It also allows a quick move between pages.

Activate “Page Manager“

Navigation Manager MenuInvoke Navigation Manager from the Start Menu/Programs/Triggerfish item.

Before working out how to set up the Navigation Manager from scratch, we need to look at the menu. If

you were using the Navigation Manager before already, after opening it you will see the last setup that

was in use. In case this is the first time Navigation Manager is used, a window as shown above willappear. In order to see the full range of options in the menu a new Pane (or “Main View” Window)

needs to be created. This can be done either from the “File” menu (File/New), or by using the keyboard

“Ctrl N” or by clicking on the “New” icon:

A small window appears which prompts you to enter a name ( Title) for the new Tab/Pane. You also have

to decide if you would like to work with Tabs (Main View) or Pane. Once you have entered a name and

made your choice between Tabs or Panes, click OK.

The window looks now a little different with the first page you have created. The new page also shows up

in the Page Manager list.

It needs to be pointed out that in general the Navigation Manager remembers all settings on Exit. And

when opening the next time it appears with exactly the same configuration. But this setup might not bethe one you were expecting: mistakes happen, for example one of the pages could have been deleted or

graphs changed by mistake. It is quite likely that you will have several pages setup for your End of Line

Report with loads of different graphs, perhaps colour coded etc. It would cost a lot of time to set


5/53


Page 5 of 53

everything up again from scratch. To avoid this you will find now an Option “Export Pages” in the “File”

menu to save your configuration that you want to use.

In case the setup gets lost, you can easily import the pages again using the appropriate option as shown

above.

In case it is required to re-generate an EOL Report, this can be done using the “Import XML Log” option inthe “File” menu. The XML Log is automatically saved for each sequence and can be found in

C:\Logging\Shooting\. This will be discussed more detailed in a different chapter.

“Print Report” and “Print Page” apply to EOL Report and will be discussed later in a different chapter.

The “Close” option shuts down a window – keep in mind that on Exit this setup will be saved by

Navigation Manager and the window will not show up any more when opening it again (unless you have

saved your setup and can import the pages …!).

“Exit” shuts down NavManager entirely.

The “Edit” menu is self -explanatory and does not need any further explanations. Just be aware that theitems are not available when in “Shooting” mode. This is also valid for the icons in the toolbar.

The “View – Toolbars” menu gives the option to activate different toolbars/icons. “Time Control”

activates a Toolbar with “Freeze Time”, “Show Full Task” and “Online to Hydra” icons.


6/53


Page 6 of 53

With “View - Panes” the Tools Pane in the NavManager can be activated.

“Page Manager” has already been mentioned above.

When selecting “Memory Manager” another window appears:

This indicates the memory usage:

Current: updates each time the Memory Management dialog is opened giving an indication of how

much memory is currently stored, updated each time the Memory Management dialog is opened giving

an indication of the length of time the current data spans.

Limit: Limits the amount of data (in Kilobytes) that can be stored in memory.

Page 7 of 53

Unseen: There are two types of data, Seen and Unseen. Seen is data sources being displayed and

unseen is data sources that are currently not selected to be displayed. This limits the time that data for

unseen sources is held. For example if this field is set to 1 minute and you added a graph half way down a

line you would see the last minute of data being displayed when the graph is created.

“Retain all of the current task” option overrides the above information and keeps all of the seen data

for the current task.

“Solved Positions”: here you can select which solved positions you want to be available for Source

Selection.

When selecting “View – Cover page” a new window showing the cover page for the EOL Report appears

that can be setup as per user’s convenience. The EOL Report will be discussed entirely in a different

Chapter later.

“Freeze Time” just stops the NavManager until you deselect this option:

“Show Full Task” zooms out to display the data of the entire line, deselecting it displays the previous

zoom level:

The “Online to Hydra” icon needs to be activated when recording online. It needs to be off when

importing from XML Log. An activated “Online to Hydra” icon is shown on the pic below to the left, the

de-activated icon to the right:

New SetupInvoke Navigation Manager from the Start Menu/Programs/Triggerfish item.

For a new setup you need to define Tabs or Panes, which you can design individually. It is possible to

create multiple Tabs/Panes in order to group similar data. This way you can organize the displays andmake the online QC more accessible.

To create a new Tab/Pane, select File/New (or hit the New icon on the menu bar).

.

A small window appears which prompts you to enter a name ( Title) for the new Tab/Pane. You also have

to decide if you would like to work with Tabs (Main View) or Pane. Once you have entered a name and

made your choice between Tabs or Panes, click OK.

The Tab or Pane should have been created and the title should be displayed in the title bar, as you can

see in the picture below. It also shows a possible layout of the QC.

It is possible to move the Tabs around, in case you would like to change the order. Just click on the Tab

you want to move and drag it to the position where you want it to be. But be aware, that the order of the

Tabs/Panes cannot be saved. When re-opening NavManager or importing Pages from xml, the order of

the Tabs/Panes will always be exactly in the order you have created them. The Page Manager would look

like this:


10/53


Page 10 of 53

Within the Navigation Manager application you have similar features available as in the other Triggerfish

applications, i.e. moving the panes to a preferred position in the window.

Looking at the “Page Manager” options above you can see the buttons “New”, “Delete”, “Edit” and

“GoTo”. Moving Tabs/Panes here is NOT possible.

To create new Tabs or Panes you have now different options: from the File menu, using the icon or with

the “Page Manager”.

Before setting up the Panes/Tabs for Online QC or for the EOL Report (or for both), it might be a good a

idea to consider which Tabs/Panes you want to create and what they should contain and therefore in

which order they should appear in the NavManager. Even though you can move all Tabs/Panes around

and set them into the preferred order, NavManager does NOT remember the order of the Tabs/Panes.

Whenever you re-open NavManager or when you import the Pages that were saved, the Pages will

always be show up in the same order as they were generated. It might help to use a leading number in

the name for the tab or a prefix that indicates if it is meant for online use or EOL Report.

However, the “GoTo” button in the Page manager makes it very easy to move between pages!


11/53


Page 11 of 53

Adding Data ObjectsAfter you have created a new Tab or Pane, you need to define what type of data should be available for

the QC. It is possible to define multiple displays within a Tab/Pane.

You have the choice between Time Graphs, Tables, Age Indicators, Frequency Plots, Target Plots,

Bearings, Vessel Map or Record Writers. All these “Data Objects” are listed in the Tools Pane, which

shows up by default on the right hand side of the window. If you cannot see it, navigate to View/Panes

and ensure that the Tools are ticked.

To pick and use any of these objects, just click and drag it onto the Tab you wish to define.

The following are some explanations of the available “Data Objects”.

Time Graph: this plot can be used when you want to monitor data on a shot-

by-shot basis, for example.

Table: if you prefer to look at numbers instead of graphs or wish to see some

numbers in addition to the graph, here is your tool. You can select the same

items and display the data in a table.

Age Indicator: for some items you might want to monitor the age of the data.

This can be helpful for example to catch faulty equipment right away or

detect incorrect settings for a device.

Frequency: this display is a similar display showing the frequency of the data.

It is useful for monitoring faulty devices e.g. a faulty compass on the

streamer perhaps?)

Target Plot: displays a scatter plot to keep an eye on the main positioning.

Bearing: displays the CMG in form of a …………

Vessel Map: to display Vessel, Guns and Streamer

Record Writer: if you wish to dump some data into a file

Once released in the appropriate Tab/Pane another window shows up in which you have to define thesettings of the display item. These are now described individually.

Tools Pane


12/53


Page 12 of 53

Adding a Time GraphTo add a Time Graph, navigate to the Tools Menu, click and drag a Time Graph onto the Tab you are

working with.

Another box should be displayed now where the Graph Settings have to be defined. In this window you

decide the general layout of the graph.

It begins with a title for the graph. It is possible to keep the default title, which displays the Vessel name,

Line name and Sequence number. If the title box is ticked you are able to edit the text.

Text with a leading % character refers to a value or name already defined within the Triggerfish System.

The other text is been displayed as typed in the box. It is possible to format the text by using the “Font”

button.

There is also an option to display a legend.


13/53


Page 13 of 53

Primary/Secondary Fields: In these sections you select the data items to be displayed. These two different

fields are very practical when you wish to overlay graphs which values do have different units. For

monitoring the SP Interval you might want to overlay the SP Interval in seconds and a different graph

showing the interval in meters. Here you would define one graph in the Primary Field, the other in the

Secondary field.

All this is to define the “outer format” of the Time Graph. It might be a good idea to set this up at a later

stage, after you have defined your data items for the display.

Now we want to select some data for the display by clicking on the “Add” button as mentioned above.

With this button a new dialogue is activated, where you select the data for the graph. There are different

options to select data, setup the graph and also give it a name.

You can enter a description for

the Y-axis values, for example

the units (meter, degree, CMGetc)

If you wish to display

statistical data within the

graph – or as a table –

select the items here.

This section helps to setup

the Time axis (X-axis) of

the graph.


14/53


Page 14 of 53

We will look now at these options in more detail. The data selection works more or less on the same

principle for each of the Data Objects listed in the Tools pane.

First you have to pick a “Source Filter” to use.

Depending on your selection for the

filter (Vessel – Streamer – Guns) you

will find different Datasets in the

section “Source” according to the

configuration in the Triggerfish

System Editor. The example to the

right shows available nodes for the

Vessel Triggerfish, the next is an

instance where the Guns are selected

as Source Filter.

Once the filter is selected, a “Type” has to be picked. There are two options, “Observed” and “Derived” –

which basically stands for “Raw” and “Processed”. The selection of the “Type” has an influence on theavailable “Attribute”. This is the place where you finally select the data to be displayed in the graph.


15/53


Page 15 of 53

Again, depending on your selection you will have different “Sources” available, as well as different

“Attributes”. It is just common sense that a Type “Observed” must have different options than a Type

“Derived”. The picture below shows how to select the bearing for an rGPS node defined. Because Range

and Bearing are raw data, we will find these options when selecting the Type “Observed”. Attributes for

“Derived” data for a rGPS Node would be for example the solved position (Northing, Easting), CMG,

Distance Along/Across etc).

You might have noticed

already, that the “Name”

and the “Formula” field

did auto fill when you

have picked the

“Attribute”. The Formula

field cannot be edited and

we will look at this a little

later. The Name field

defaults to the name of

the dataset you have

picked, but can be edited,

if you would like to add a

more detailed description

(for example: G1L1 –

Bearing for the selection

below). This text also

shows up in the

description for the

Legend.

Finally, you have the

chance to choose a

design to be displayed. In

the section “Appearance”

you can select if you want

the graph to be displayed

with a line or symbols and

assign a colour. There are

drop down menus for

your selections.

It has to be pointed out here, that the Sources available for a “Derived” position may vary, depending on

the setup of the Memory Manager. In this dialogue is an option to select “Solved Positions”. In the pic

below (left pic) the default settings can be seen, with “GPS Nodes” ticked to be available. This is in

general sufficient for the NavManager display items. The pic to the right shows the available Source

Selection with these settings.


16/53


Page 16 of 53

In case any other “Solved Positions” are needed, the appropriate items have to be ticked in the MemoryManager, see example below with the Echosounder Node selected:

Similar Options can be found when enabling Guns, Gun Depth Sensors etc for Tables.

Echo Nodes selected

in Memory Manager

Echo Sounder derived Position available

in Source Selection, with appropriate attributes.

therefore


17/53


Page 17 of 53

By clicking OK you will be returned to the Graph Settings dialog where you can finish adding labels and

deciding on the statistics you wish to add to the graph.

You can see in the example below that the Title has been edited and the “Show Legend” option is ticked.

This display is setup for 3 rGPS ranges on the gun array. The Label has been changed to “Meters” and also

the setup for the Time Axis is not default. The numbering is set to Shotpoint instead if a Timestamp and

the Label for this axis changed accordingly. There is an option to display data even when offline is

selected. In this case there are no statistical values added to the display. The Unit field is greyed out and

filled in automatically. The tick boxes give you the option to set a scale for your Y-axis. The third tick box

invokes to invert the direction.

After pressing the OK button the newly added graph will appear on the Tab/Pane. Use the mouse to

resize the window as you wish and position it to a suitable spot on the Tab/Pane.

With the settings used above the graph should like this:

You can enter a description for the Y-

axis values, for example the units

Set a Min/Max value for the Y-axis to

scale

Invert the direction of the graph

Configure the Time Axis and decide if

you wish to include offline

Configure the scale of the Time Axis


18/53


Page 18 of 53

The Legend shows up per default on the right hand side of the window but can be moved by clicking and

dragging to an appropriate position. In this case the Legend has been moved right underneath the Title of

the window.

It is also possible to adjust the scales by using the mouse, if you are not happy with the initial numbers

that were used, or the scale you have selected is now inadequate because the real value exceeds the

scale (rGPS bearing might change a lot when the current changes …!!). Using the mouse to adjust the

scale is very easy. Simply move the mouse on top of the scale that needs adjustment until the pointer has

changed to the “move” style . Now you can use the mouse wheel to zoom in or out. There is also an

“AutoScale” option when you right click the mouse while the pointer is on the scale.

Pressing the left mouse button while on top of the scale changes the mouse pointer back to and lets

you move the graph up or down in the window without changing the actual scale – only the position of

the graph. The same feature is available on the Time Axis and you can move the graph to the left or right.

Moving the mouse across the graph display area will bring up a crosshair with the actual values of the

mouse position on both axis printed on it. As you move along the values of course adjust. This is a nice

tool for picking questionable data – for example.

“Auto Scale” works for both

axes!


19/53


Page 19 of 53

Following now an instance where both, Primary and Secondary Field, are used and different units are

merged in a single graph. This setup is also configured to display a statistical table in the window.

By the way, if you add a dataset in the Primary Field which does NOT have the same unit as the one

defined firstly, the Navigation Manager will automatically drop this dataset in the Secondary Field.

With these settings as shown above you will produce a graph that looks like the one below.

Because the Statistics have been ticked to be displayed in a table the printed values will appear in thewindow. Most likely they will not show up in the correct spot where you would like them to see. Just click

and drag on the table to move it into your preferred position.

the graph


20/53


Page 20 of 53

It would be possible to display the statistical values as another graph within this window – this depends

on the users preferences.

The Time Graph provides also a few other features.

Looking at the “Source

Selection” dialogue

where you pick the

data to be displayed

are a few more buttons

to explain.

“Difference” between

CMG and Gyro is

selected here to display

the crab angle.

Difference: pressing this button will produce a Formula (minus sign) being entered in the Formula row.

But there are some rules to follow when setting it up. First you pick your data source as usual, and it will

show up in the Formula row. Now you press the “Difference” button and this will bring up the minus sign.

Now you select the second dataset that you wish to subtract from the first. Be aware that you have tostart with your selection from the very beginning, meaning “Source Filter – Type – Source – Attribute”.

Now the Formula is filled in and the graph will display the difference of the selected datasets. This could

be useful if you want to monitor the crab angle of the vessel to be aware sudden currents.

Scale: this window shows up when you press the “Scale” button. The

value you enter serves as a multiplier for the scale of the X-axis of the selected dataset.

An example would be the Vessel BSP. In Triggerfish the speed is displayed as m/sec. But the user would

like to see it as knots. Just enter the correct multiplier and you will see the Vessel BSP in knots with these

settings:


21/53


Page 21 of 53

Offset: this window appears when pressing the “Offset” button. You

need to enter an absolute value to be added to the nominal scale of the X-axis for the chosen dataset.

This can be helpful if you would like to overlay rGPS ranges from Gun pods with Tailbuoy Ranges from a

Streamer.

Trend: when using the “Trend” button the formula row will be updated with a function. The graph for the

selected dataset will contain some sort of filtered/smoothed data.

Detrend: this will cancel a selected Trend option and display data as normal.


22/53


Page 22 of 53

Adding a TableYou might be interested in looking at some values in a table. Navigation Manager gives you the option to

do so when selecting the Data Object “Table” from the Tools Menu. You should find the Tools Menu by

default still at the right hand side of the Navigation Manager window – or wherever you have placed it.

You have to follow basically the same procedures as for the previous Time Graph: from this menu clickand drag a Table onto the Tab you are working with.

Now the “Table Settings” box should be displayed. The design of the dialogue box is similar to the one

from the Time Graph and to all the other “Settings” boxes for all the “Data Objects” available. From this

dialogue you can setup the Table and select the Data you wish to be displayed.

You will recognize the Title row, which can be edited per your wishes. And again, you have to pick a

“Source Filter” (Vessel, Guns or Streamer etc). Once you have made your choice, you will have your Data

“Sources” available. Depending on the selected Source and Types (“Observed” or “Derived”) existing

“Attributes” show up. You have probably noticed that Source and Attribute are sorted into Rows and


23/53


Page 23 of 53

Columns. This represents Rows and Columns in the Table. Default is to have the Source in rows and the

Attributes (Data) in columns, but it is possible to swap those by using the switch button .

A useful Table might be some sort of GPS QC. An example is shown below.

Pick the Vessel as “Source Filter” and select object you are interested in as “Source”. In this case here you

have to tick the box next to the objects name. After you have selected the first Receiver, decided if you

are after “Observed” or “Derived” data. In this situation we go for the “Observed” (Raw Data). From the

available Attributes we pick for example some DoP’s, Correction Age, Mode etc. Now you can select all

the other Receivers you wish to monitor – the Attributes will stay the same. Click OK and the newly

defined Table appears – which will most like need to be resized.

The Table just defined should look like the following:

Ticking this box results in “Short

Names” for the Attributes, i.e. Sta

for Stations etc.

Switch button


24/53


Page 24 of 53

This Table has Rows and Columns swapped. You see the “Source” (CNav1 and CNav2) in columns and the

“Attribute” (Data) in rows. It is also possible to swap rows and columns right in the Table window instead

of bringing up the Table Settings dialogue again.

Click in the top left corner of the window to swap rows and columns.

You can resize the window by clicking on it and then move the boundaries.

Note:

As mentioned above already, it might be that you are missing some “Solved Positions” for your display

item. Then open the “Memory Manager” (View – Memory Manager) and select the solved Positions of

interest.


25/53


Page 25 of 53

Adding an Age IndicatorAdding an “Age Indicator” might be a good idea to monitor devices and ensure they have not dropped

out. It is a quick reference to check if everything is working properly.

To add an age indicator, just follow the same principles as for the previous plots, navigate to the Tools

Menu, then click and drag an “Age Indicator” onto the Tab you are working with.

The following “Age Display Settings” window looks a little different compared to the others we have seen

before, but of course this is a complete different type of display.

To select the device you wish to monitor click on the

“Source” button of the window (the clock). The “Source

Selection” window should now show up


26/53


Page 26 of 53

And here you have to pick the device you want

to monitor. Again, “Source Filter” first, then the

device itself as the “Source”.

Back to the “Age Display Settings” dialogue, because there are some inputs to explain.

Depending on the device you have selected for

monitoring, you are probably aware of how often

to expect the data to come in. The settings window

here lets you set a “Time to Fail” – which is

basically a timeout. Once the timeout value is

reached and no new data are coming in, the colour

starts changing from green to light green, yellow, orange to red – until it gets a new set of data and it

turns green again. The “Hold Time” in this dialogue lets you setup for how long you wish to keep the

status “green” (good!) before it changes the colour.

Let’s also look at some compass data as an example. Compass data are expected to come in with everyshot. So the “Time to Fail” is set to an average value for the SP interval, let’s say 12 secs. Leaving the

“Hold Time” at zero changes the colour right away. To see the effect, a single compass is set up in

different ways: timeout is always 12 secs, the “Hold Time” varies for each display (0, 5, 9 and 12 secs)

The screen grabs below show the status and the colour code of the indicator for the compass at different

intervals and with different settings for the “Hold Time”.


27/53


Page 27 of 53

Apparently the colour “Green” means the status is good – according to your settings!! – and “Red”

indicates missing data.

Just have a play with it and try the different settings for a better understanding.

Once you have picked and set up all the devices you want to monitor, you might end up with display

items as seen below:

After ~4 secs After ~7 secs After ~10 secs

“Hold Time” set to 0





28/53


Page 28 of 53

Adding a Frequency IndicatorIf you want to know and monitor how often data are coming into the system, the “Frequency” Plot might

be an option for you. Again, you open a new “Frequency” Plot by selecting the correct Data Object from

the Tools pane, click on it and drag it onto the actual Tab.

The “Frequency Plot Settings”

box is displayed here. In themeantime you are already

quite familiar with the layout

of the dialogue boxes and it

should look familiar to you.

Because it is a device you

want to monitor (and not the

data themselves) you will find

here again a “Source Filter”

and “Sources” for yourselection. Following the same

principles as before, you can


29/53


Page 29 of 53

select which devices to use and how your plot shall look. Again, you have to decide what timeout value to

use. The value “Time to Fail” needs be set up properly. “Hold Time” is here defined in the same way as in

the “Age Indicator” plot previously explained. You might want to set up a set of devices for monitoring for

a quick reference that everything works fine. A Frequency Plot once setup should look more or less as the

shown above.

It needs to be pointed out, that the display always depends on your settings for the “Time to Fail” (and

the “Hold Time”)

The colour “Green” is of course indication a status “good” – so frequency of incoming data is ok according

to your settings. The colour is changing depending on how long it takes until the next data are coming

into the system. Colour changing again from green, to yellow to orange to red, which means no data.


30/53


Page 30 of 53

Adding a Target PlotThe next item on the list of Data Objects in the Tools Pane is the “Target Plot”. This display enables you

to monitor data in form of a scatter plot. Procedure for starting and setting it up is similar to what we

have seen already. You have to start the “Target Plot” from the Tools Pane by clicking and dragging it

onto the Tab you are working with.

A new window appears which is the dialogue for

the “Target Plot Settings”.

But before you finalise the layout of the plot you

should consider what you wish to look at.

For example, a scatter plot is suited very well for

monitoring GPS positions. It could also help to

check if your antenna offsets are correctly defined

in your system configuration.

As usual click on Add to invoke the “Source

Selection” window.


31/53


Page 31 of 53

In the scatter plot described here we want to see the GPS positions of the receiver and also see their

position relative to the VRP (to verify offsets). To configure the “GPS Scatter Plot” do the following:

Select your “Source Filter” and “Type” first. For a vessel GPS plot we need the Vessel as a

Source and the Type “Derived” to get a list of Sources and Attributes we want to see.

Once the first GPS Receiver is selected, it shows up in the Formula row.

Now you need to press the “Difference” button, to create a Formula, and you are

expected to select a second “Attribute”. We will pick the VRP for our purposes as shown below.


32/53


Page 32 of 53

Now define the “Appearance” of your figures – for a scatter plot you might want to select a point-design

instead of a line.

You also might want to edit the name. Then click OK. Now you have to finalise the “Target Plot Settings”,

for example edit the title of the plot, enable a legend etc.

For “Orientation” select in this

case “Crossline – Inline” because

the values in reference to the

VRP shall be displayed.

The “History” selection here defines

dimmed colours and fading over time.

The value for “Show historic points”

updates along the line if you don’t edit

it. If required, the entire line can be

seen.

Select an appropriate scale for

the display item.

Edit the “Title” of the display

item.

Select the desired Font.

After clicking OK on that window your new defined scatter plot will appear in the Tab you are working

with.

Below you can see an example. There are 2 GPS Positions setup to show the difference to the VRP.

The display item in the top shows the

Scatter plot defined above; you should

see a pile of dots scattered around the

values for the antenna offsets

The one below is a comparison of GPS

Receiver Position (derived) and VRP. The

values here should be close to 0 (zero).

In both case it would make sense to

select a fixed scale for the plot:

Adding a Bearing DisplayIf you want to display headings in a different way than a “Time Graph”, the “Bearing” option might be

suitable. This “Data Object” provides a compass style display of headings.

Starting the “Bearing” Display is carried out in the same way as all other displays: select the “Data

Object” called “Bearing” on the Tools Pan, click and drag it onto your preferred Tab.

Again, another window for “Bearing Display Settings” shows up and it looks like the one below.

Same routine as usual applies here as well: you have to

select the data you want to look at in this display by

clicking on the Add button.


35/53


Page 35 of 53

The “Source Selection” window showing up now will look very familiar to you and does not need any

further explanation.

Pick the Data you wish to see (Source Filter – Type – Source – Attribute), perhaps edit the name, adjust

the appearance and the display is setup.

After you have OK’d both windows (“Source Selection” and “Bearing Display Settings”) you should see a

Bearing Display similar to the one below on your present Tab. This one is set up to show the Bearings ofthe rGPS pods (as setup above).

Adding a Vessel MapAnother option for a display is the “Vessel Map”. This module is still in progress and in the moment it

does not provide the full range of features. If you wish to add a “Vessel Map” you need to follow the

same routine as for all the other displays.

Select the “Data

Object” “Vessel

Map” from the Tools

Pane, click and drag

it onto the actual

pane.

Now the window “Map Display Settings” will appear:

From this dialog you can select the orientation, Aspect Ratio, Vertical Axis and the object that the display

is centred on.

Confirm the settings by clicking on OK and the new display will show up on the actual pane.

To configure the map the panes “Layers” and “Types” are needed as shown on the pic below. Select a

layer (for example “Vessel”) and click to the left of it and you can see the vessel shape disappearing or

showing up. This way you can enable or disable layers.


37/53


Page 37 of 53

Then use the types to enable/disable or change the colour. Colour can be changed by clicking on the

coloured square, enable/disable can activated by clicking to the left of the colour square. Unfortunately

there is no spot marked for this, so you might have to move the mouse further to the left.

Example below shows the Gun Array as Layer enabled and the Gun Centre selected to be displayed. The

Centre of Source will only show up, when the Gun Array as a layer is activated.

In case the “Layers” and “Types” Pane do not show up on the left side of the new window it is possible to

activate them – a bit tricky though:

Place the mouse over the top left corner of the map window and dotted outline of a square should be

visible. Now click on it (left mouse button) and the Layers/Types pane should open in the map window. In

the types pane there should be four icons preceding the type name (alas they have vanished). These

icons are (in order):

Visible

Show label

Colour

Line style


38/53


Page 38 of 53

The only one that is visible at all in the moment is the colour icon, so the “Line Style” can be found by

clicking to the right of the colour icon, to “Show Label” click just to the left of the colour icon and to

select “visible” click a bit further to the left.

Of course for the Map are the usual tools available either from the menu or as icons on the toolbar:

Since this module is still being worked on and not all the features a re functional yet, more details will be

added at a later stage.

Adding a Record Writer

If you wish to log some data to a file, the “Record Writer” is a very helpful tool. In many occasion some

sort of “Shotlog” is required, and if not required, it is at least very helpful if certain data are needed for a

certain time or shot point.

To start the

application you need

to follow the samerules and procedures

as before:

From the Tools Pane

select the “Data

Object” called

“Record Writer”, click

and drag it onto the

actual pane.

Now the Record Writer Settings dialogue shows up.

In the File row you have to enter a Filename to write to. You can use the Browse button to select a

suitable folder and then enter a filename.

The Field Delimiter section of the window lets you decide which file format you wish to use for the

logging. The options are Comma separated, Tab separated or Space separated.

Name (full path name, use browse

button to select folder) of the file

you want to log the data to

Select the preferred file format for

the logging.

Tick if you wish a Header Row

Select the recording preferences.


40/53


Page 40 of 53

If you wish to include a Header in the top row of the file, you have to ensure that this Header box is

ticked.

The section called Recorder Trigger lets you select your recording preference. Do you wish to dump the

data in regular time intervals select the option Time and enter the interval you would like to use.

If you wish to log the data for every shot, you have to pick the Shot option for the recording.

If none of these options are appropriate for you, the Data Receipt options might be suitable.

Below an example for a “Shotlog”. You can see the filename is entered – and this needs to be changed for

each sequence you shoot – if you wish to keep it as a shot log. The Record writer will add data to the

same file if the name is not changed.

A Tab separated field delimiter has been selected in his case and it is configured to record every shot. In

the field to the left you can see a selection of items to log to the file – just as a suggestion.

In the Record Writer Settings dialogue you have to press the Add button now in order to select data to

be written to file. Again, the Source Selection window appears and you have to pick the data you wish to

record. Same principle as usual: Source Filter – Type – Source – Attribute. If you wish you can edit the

name. That will be part of the header in the file. Example below shows the Source Selection to log the SP

number in the first column of the log.


41/53


Page 41 of 53

Confirm all settings and the “Record Writer” will appear on the actual Tab. To start the actual logging the

“Start” button needs to be clicked. To stop logging press the Stop button.

If you want to clear the log – and the files! – use the Clear button. Please be aware that using the Clear

button also cleans the recorded file!!

If you rather wish to use the Data Receipt options, you have to click on the little clock icon in “Record

Writer Setting -> Recorder Trigger -> Data Receipt


42/53


Page 42 of 53

This opens a dialogue you are already familiar

with – the Source Selection.

Here you can select the reference for the

reception of the data.

In this case a GPS Receiver is selected - thismeans, that all data that will be recorded – will

be grabbed exactly at the same time when this

GPS Receiver receives data.

Selecting the Type “Navigation” would mean

selecting the Triggerposition as reference.


43/53


Page 43 of 53

Additional InformationTo edit any of the displays defined, double click on it and the settings box will be redisplayed, at which

point you can change any required settings.

To delete an item, right click on it and select Delete from the list.

The menu that appeared also gives you the option to copy, paste or print the display item.

Remember, on a couple of plots you can use the mouse (wheel) to zoom in and out and change scales.

It is very important to remember to generate the NavManager EOL Report immediately after a task has

finished – before you acknowledge the “Next Task” in the Survey manager.

Even though the data are still available the Linename and Sequence number will be the one of the next

task.


44/53


Page 44 of 53

Generating End-Of-Line Reports.Now the Navigation Manager should be set up for a nice and easy online QC. This setup can be sued for

the entire job (or even for next jobs?) as long as the configuration does not change! Then of course you

will have to adjust the displays.

When “designing” and setting up all the Tabs/Panes that you wish to look at, you might want to keep in

mind, that everything defined and configured in the Navigation Manager can be used for an End-of-Line

Report. When organizing the Tabs/panes and adding “Data Objects” you could consider the EOL Report

and choose the layout according to what the EOL Report is supposed to contain. Each Tab/Pane will be

printed in the report as a separate page.

To print an End-of-Line Report go to File/Print Report.

Select your preferences: would you like a report that

covers the entire line as defined in Triggerfish, or

would you rather enter a SP range of your choice, or is

it the current view you are interested in?

Select the Page Orientation you prefer.

Don’t forget to set up the Printer!

It is possible to add a Cover Page for the Report. Select

this option from here and click the “Edit Cover Page”

button to set it up.

Select all the Tabs/Panes that are supposed to be part

of the EOL Report; you can also move them into the

desired order for printing.

Tick this option if Footer shall be added to the pages.

The row can be edited as per your requirements.


45/53


Page 45 of 53

Most likely a Cover Page is appropriate for the EOL Report, which contains details about the Job, Client,

perhaps vessel name, Line name, SOL and EOL Shots and Times etc. It is possible to set up a Cover Page in

NavManager according to the Crew’s (or Clients!) demands. The Cover Page is accessible via the “Print

Report” dialogue (see pic above) or via the “View – Cover Page” menu.

Either of these options opens

a new window which looks

like the one below:

On the right hand side of the

window in the section called

“Captions” you can find all

items that you might need and

wish to be shown on the cover

page.

Each of these items will open

another window that can be

edited and displays the

required data which are

stored in the Triggerfish

system.

The same procedures andrules apply here as for all the

previous displays that were

set up:

Click on an item, drag it to the

window and another dialogue

box will appear called

“Caption Settings”


46/53


Page 46 of 53

The newly opened “Caption Settings” dialogue allows you to design the layout of the selected display

item, i.e. choose the Alignment Font and Font size etc. by using the appropriate buttons and pull down

options.

When the Caption “Title” is selected (for example) a dialogue shows up as shown above. The text in the

row can be edited as per your requirements. As mentioned before, text that starts with a leading % is a

Variable that will always refer to a value which is stored somewhere in the Triggerfish system.

%vessel – this is the Vessel Name as defined in the System Editor.

%line - this is the Linename defined in the Shooting Task in the Survey Manager.

%seq - this is the Sequence Number defined in the Shooting Task in the Survey Manager.

Or when “Survey” is selected this window opens with %survey being the variable and the word “Survey”

in front of it shows up as text (description) on the Cover Page.

It is also possible to select Shotpoints or Times, in example below the “First Task Point” is selected.

VariableText

Format the displayed items

Page 48 of 53

Once you are finished and happy with the setup of the Cover Page, you can exit the window either by

using the File/Close option from the menu or by hitting the x in the top right corner of the window.

Now you are ready to print the EOL Report – of course after you have checked the Printer Settings!

This might also be a good occasion to export the NavManager configuration – remember …

Importing XML Log to generate End-Of-Line Reports.In case the EOL Report gets corrupted or the data are not present anymore because a new task is already

running, there is still an option to generate the Report at a later stage.

In the SystemEditor (Vessel – Shooting Options – Logging Options)

a folder is defined where for each task a XML Log file is created. This contains all data from the moment

when the Vessel Mode is set to “Shooting” in the Survey Manager until the end of a task. By default this

file can be found in the folder C:\Lgging\Shooting.

NavManager gives the option to import this xml to generate an EOL Report in “offline” mode. To

accomplish this the NavManager needs to be “offline”, meaning it does not connect to Hydra (database)

in order to retrieve current data for display.

On the online Triggerfish machine Hydra is normally always connected. This can be seen and verified

checking the “Online to Hydra” icon in the toolbar.

“Online to Hydra” is highlighted

and outlined by a square:

NavMan connected to H dra

“Online to Hydra” is not

highlighted:

NavMan offline


50/53


Page 50 of 53

The Status can be changed by clicking on the icon. When in “Transit” mode you might want to try and see

what happens when the NavMan is set to offline – you will not see any data. And when activating Hydra

again, there will be a gap in the data.

If it is required to generate a new EOL Report for a sequence that was shot earlier Vessel Mode should be

in transit, since it is not recommended to mess up online data!

Then Hydra needs to be disconnected. Check the icon and ensure you see the icon as shown in the 2nd

pic above.

Assuming the configuration of the NavManager is still as required, you can go straight to “Import XML

Log” in the File menu and select the appropriate log.

If the NavManager configuration is not as required, the Pages that have been saved before need to be

imported first.

As soon as the correct XML file has been selected the import starts. You can monitor the import and

ensure all SPs are present while watching the “Import Progress” window, which shows up immediately.

Once the import is finished you can generate the EOL Report right away as described already before.


51/53


Page 51 of 53

It is also possible to use the “import” option on a complete different machine, a computer which is totally

independent from online acquisition and not even part of the Triggerfish Network.

To accomplish this, the following needs to be done:

Triggerfish has to be installed on that computer as normal, with Hydra Server and Hydra proxy running. Aseparate license is not required, because this computer will not be used for online acquisition.

The current vessel configuration will be needed, so export the SystemEditor from the “online” machine

and copy it to the computer to be used and open it.

In this particular situation, where the NavManager import option will be used on an “offline” machine,

the SystemEditor needs to contain a NON LOCAL vessel. Normally, you do have a single local vessel

defined (streamer, see below)

or one local vessel plus several non-local vessels, if a Multi-Vessel operation is in use.

Now the configuration of the vessel, which has originally recorded the line needs to be imported as a

non-local vessel: open the SystemEditor and select File – Import – Configuration from XML …


52/53


Page 52 of 53

Once the correct file is selected another window appears and here you have to deselect the local vessel:

Now a second vessel is available and it is defined non-local. Do not worry about Computer name or other

settings – just leave it as an exact copy of the online used configuration.

It is not possible to save the configuration after the import, since no changes have been made to the local

vessel. Triggerfish does not allow any changes to be saved in a non-local vessel per default. To save and

keep the configuration now, you can just edit something in the local vessel and then hit the save icon.

Now the SystemEditor is saved with both, local and non-local vessel.

The next step would be to set up NavManager and import the configuration which has been saved earlier.


53/53


Ensure NavManager is not connected to Hydra

Now the import of the XML Log can be started – exactly as described above.
