This driver is used to decode the iXSEA / iXBlue proprietary NMEA message which starts with $PHOCT.
This message is outputted by the iXSEA / iXBlue:
- Octans - Motion & Heading
Motion and heading are decoded depending on the selected/entered slot value(s).
Apart from the Motion: roll, pitch, heave and Heading observations the driver decodes the following additional (miscellaneous) observations:
- sway speed
The additional observations are decoded by a Miscellaneous System.
The Heave for the TAH message can also be used as an alternative depth source when using a Fall Pipe ROV.
