Kongsberg Binary Delayed Heave (UDP Network) - 23

Description

This driver supports systems that can output the KM Binary format.
Note that this not the KMALL Binary format, for this see the KMALL driver.

Systems supporting sending the KM Binary format.
Applanix POS MV WaveMaster.
Kongsberg Seapath 380.

The supported system types for this format:
Position Navigation System.
Gyro Compass.
Pitch Roll Heave Sensor.
Time Synchronization System.
Acceleration Velocity Sensor.
Miscellaneous System (Delayed heave).

Definitions

Data format

Little endian (the least significant byte is transmitted first). Float is according to
IEEE - 754.

Dgm length

The total number of bytes in the datagram.

Dgm version

The version is incremented if the datagram format is changed.

Timestamp format

Epoch 1970-01-01 UTC time, ignoring leap seconds.

Position and height

At user defined sensor reference point. Position in decimal degrees.
• Latitude: Negative on Southern hemisphere.
• Longitude: Negative on Western hemisphere.
• Height: Positive above ellipsoid.

Positive roll

Port side up.

Positive pitch

Bow up.

Positive heave

Downwards, at user defined sensor reference point.

Heading

True north.

Error fields

Sensor data quality: RMS

-1 = not implemented
