Rate of turn, ROT:
First is this data mostly calculated by a gyro or a satellite -compass.
Seconds is, what I'm aware of, the ROT data for own ship not used by OCPN anywhere. It's though reported by the AIS type A target's detailed information. (AIS type B does not report ROT)

Thesse are the NMEA0183 sentences supported by OpenCPN
https://opencpn.org/wiki/dokuwiki/do...nmea_sentences
HDM HDT and HDG are supported. Also see
Terminology
Please see this page of the
Manual Options >Ship > Own Ship
At the top are two optional selections for showing COG and Heading vectors if you have the data available.
Incidentally I believe that the
plugin Dashboard_Tactics will support SignalK and thus Nmea2000, which might help get the data into Nmea0183, depending on your setup.
BTW someone had trouble with the Clipper below, because it was not using standard sentences, I think, and I do not
recall if it was
solved. Perhaps do a search on this forum, or maybe a reader here knows.
Later: I think it may have been
solved by using NmeaConverter.
