Add support for PGN 127257

[sarfata]

It would be great to have support for PGN 127257 so we can transmit and receive attitude messages (heel/pitch/roll).

It is documented in Canboat:

{ "Attitude", 127257, true, 7, 0,
  { { "SID", BYTES(1), 1, false, 0, "" }
  , { "Yaw", BYTES(2), RES_RADIANS, true, "rad", "" }
  , { "Pitch", BYTES(2), RES_RADIANS, true, "rad", "" }
  , { "Roll", BYTES(2), RES_RADIANS, true, "rad", "" }
  , { 0 }
  }
}

It would be good to know what is the reference framework too. I am guessing Yaw is relative to true north. Not sure about pitch and roll.

Hi,

No Idea. Do I add it and try with NMEA Reader, what it shows?

That would be great. I think if someone could capture data from a sensor that sends them (I think some of the Airmar wind sensors send that information) that would be great too.

Hi,

Yaw could be also relative to your course over water. For aircrafts it
has been defined (at least on some referencies) angle between your
course over air.
pitch = positive, when your bow rises
roll = positive, when tilted right

I just added attitude PGN 127257. I could only test it with NMEA Reader. It also showed Yaw as negative value, so it may be defined as I mentioned in similar ways as in aircrafts as an angle between vessel course over water.

Thanks. I will try with my Raymarine i70 but I doubt it will be supported.
