SmartWorx Viva – How to Record Static Observation Data On-board GS

Receivers in Rover Mode

Firmware Version 4.01

JAN12

The Viva system provides many options that improve on needed hardware in the field. One of

these options is the ability to store static GNSS observations directly to a SD memory card in the

GS receiver. There are options for storing either the Leica MDB format or RINEX formatted

files. Each of these options requires a license key to open these capabilities. This guide will

provide the steps needed to start a static observation session with a single CS controller and a

GS receiver. Please remember that a single CS controller can be used with multiple GS units to

start the static sessions. This frees up the CS controller to be used in other field requirements

while the GS receivers are logging static data.

In this example a Viva Working Style has been created for a user’s typical settings for logging

static data. You can create your own Working Style for static survey. The main settings for

recording static data are shown in next section of Guide.

Static Observation Recording Options

From the main menu select the Instrument icon

Page | 2

Next, choose the GPS settings.. icon…

Next, select the Raw data logging icon…

Page | 3

Select the box next to Log data for post-processing and the options will be viewable. There are

options to log data to the CS controller or the GS receiver. In this case we wish to use the CS

controller for another task after we start the static session. So in Log data to: field choose GS

sensor and the data will be stored on SD card in GS receiver. In the Logging starts: field choose

Only within survey so that you can name your Point ID, input antenna height, and code if

needed. In the Log data when: field select Static. In the Rate: field choose the epoch interval

you wish to record observations. In the Data type: field you can choose either Leica format

(MDB) or RINEX. In this example we will be logging data in Leica format (MDB) to import the

static data into Leica Geo Office (LGO) for processing.

The settings shown should be saved in a Working Style for convenience. If a Working Style is

created for static surveys the user will be able to load the working style quickly instead of

manually changing settings.

The SD card that will store the GNSS observation should be placed in the GS receiver. The

following Figures A and B show an example of the LED configuration for the GS receivers when

a formatted SD card is inserted. When the SD card is inserted into the receiver the LED next to

the SD card icon will turn steady green. This means the card is recognized and available for

data recording.

Performing Survey for Static Observations

To start the static survey and have it store to the SD memory card in the GS receiver after you

have made the proper settings, simply choose the Go to Work! icon from the main menu.

Next choose the Survey icon…

You can now enter the Point ID:, Antenna Height, and Code as normal … and then select F1

(Meas) function key. It is important that you enter all of the information for the survey point

before you select to start measuring observations.

After you select to start measuring observations you receive the message shown. Select the F6

(Yes) function key to exit the Survey application so that you can move to another part of your

survey project. The GS receiver will continue to log raw data.

SmartWorx will now report that the point has been stored. The job files will be sored on the CS

controller. The GNSS raw data file (.m00) file will be stored on the SC dard in the GS receiver

Before you leave the GS receiver, observe that the SD card is recording the raw data. The LED

for the SD card will blink green as shown in Figures C and D when the SD card is recording data.

Saving the Static Survey Data File and Ending the Static Session

When you have collected static data for the set time needed simply turn off the GS receiver.

There is no need to reconnect to the GS receiver with the CS controller. The file is closed and

saved when the receiver is in the process of powering down from operation.

Importing the GNSS Data in Leica Geo Office

So, you have completed your field work and are now ready to process the static data in Leica

Geo Office (LGO). The main data job is on the memory device used in the CS controller and the

Leica GNSS raw data file (.m00) is on the SD card in the GS receiver.

First Transfer the data job from the CS controller with the normal data download method your

company uses with Viva. The file will still be located under the DBX directory on the memory

device used on the CS controller.

The GNSS raw data is located under the DBX directory of the SD card used in the GS receiver.

Please note that there are no individual job folders kept on the GS receiver. Each GNSS raw

data file (.m00) will be named with the last four digits of the serial number of the GS unit, the

data, and time of file creation. In the example shown the last four digits of the serial number

for the GS receiver is 0013, the job was created on January 18, and was created at 1:13:59 pm.

So the file name is 0013_0118_131359.m00

To complete the data download, please copy the (.m00) file from the SD card and place it in the

same directory for the DBX which was downloaded for the CS controller for the job. You can

have multiple (.m00) files for multiple receivers that were started for GNSS static observations

from the same working job on the CS controller being used to start the receivers.

Next, create a project as you would normally in LGO. When you import the GNSS raw data into

the LGO project for the static session observations you will need to highlight the name that

appears for the DBX from the controller and also the (.m00) file from the SD card and import

them simultaneously.

Once the raw data has been imported you can see that the point name, antennae setup, height,

and code are all imported into the LGO project.
