Vessel DockingVessel Docking “20 / 20 / 20” Essential performance for reliable

vessel docking 20mm accurate position, update rate of 20Hz, latency of

20ms

Centimeter or Submeter operation During Docking maneuvers receivers provide rapid

centimeter level accuracy’s Also seamless switch to submeter operation for route

navigation during a crossing and then back to centimeter accuracy’s at the next port.

Seamless NavigationSeamless Navigation

Example - Stenna Fast Ferry Carries 1400 passengers, 400 vehicles, 120

Trucks Cruises at 40Knots, Docks at 10Knots!!!

Multiple Navigation Information Provides specific navigation information for

selected locations on the vessel. Also provides information to ensure safe

distances are maintained from wharves, pilings and other objects.

Data Recording All positioning information is recorded and

time-stamped into a project file allowing docking operations to be examined later

Vessel DockingVessel Docking

Overcome Limitations of Laser Systems No line of sight is needed between the dock

and the vessel, Any size of vessel can be monitored with the

same system Functions at any state of the tide and will

even give you an accurate tide level, Optical systems rely on a reflected beam of

light but with GPS the vessel can be at any angle to the dock or in any weather conditions

Vessel DockingVessel Docking Conventional RTK

solves 3D vectors between a stationary base and moving rovers

Updates at 1, 2, 5, 10 or 20Hz Relative accuracy, Base -> Rover = 1 - 2cm

Moving Base RTK solves 3D vectors between a moving base and

moving rovers. Updates at 1, 2, 5, or 10Hz Relative accuracy, Base -> Rover = 1 - 2cm

Vessel Docking – MB RTKVessel Docking – MB RTK

Relative Accuracy Base to Rovers Always = 1 - 2cm

Absolute (real world) Accuracy Dependant upon corrections supplied to the

receiver designated the Moving Base If no corrections - Autonomous (20m) If DGPS corrections - DGPS (sub meter) If RTK corrections - RTK (1 - 2 cm)

Relative Accuracy is always 1 - 2cm
