Seapath Binary 26
This is a proprietary format created by Kongsberg Seatex ( http://www.km.kongs-
berg.com/seatex ) for position, attitude and velocity data from the Seapath sensor.
•
POS-MV GRP 102/103
This is a third party proprietary datagram format created by Applanix
(
http://www.applanix.com ) for position, attitude and sound speed data.
•
Coda Octopus MCOM
The Coda Octopus MCOM is a third party proprietary datagram format created
by Oxford Technical Solutions Limited (
http://www.oxts.com ) for efficient
communication of marine navigation measurements and other data. This format is
used by Coda Octopus for transmitting position, attitude and sound speed data.
Special interfaces
• Trigger input/output for synchronisation
• 1 pulse per second (1PPS) clock synchronisation signal
Doppler shifts
All new generation of multibeam echo sounders from Kongsberg Maritime have an
extended range performance by use of a frequency modulated transmitter pulse (FM),
also called chirp pulse. In the FM mode, the Doppler shift made by the movements of the
survey vessel relative to the bottom, causes a range error. This error must be corrected.
The following motion sensors have specifications that fullfills Kongsberg Maritime
requirements for doppler shift corrections
• Kongsberg Maritime – Seapath series
• Applanix – Pos MV
• Coda Octopus – F180
• IXSEA – Phins
Velocitiy sensor accuracy requirements
• Velocity: 0.03 m/s RMS
• Roll, pitch and yaw rate: 0.03 deg/s RMS
• Latency: Maximum 5 ms
• Update rate: 100 Hz
Motion sensor accuracy requirements
The accuracy of the sensor data, as specified by the sensor manufacturer, must fulfill
(preferably surpass) the following requirements
•
Roll:
0.02 degrees RMS
– An accuracy of 0.05 degrees RMS can be accepted unless you have very long pulse
length and large beam angles.
•
Pitch
: 0.05 degrees RMS
