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!!!
Vessel DockingVessel Docking
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
