Note2:
Magnetic variation
from the HDG message is only used to calculate true heading from the magnetic heading in the same message.
Magnetic variaton out in the HDG-message is however the variation currently in use in the IS15 system.
Proprietary sentences in/out IS15:
In to Is15 $PSTOK,a<CR><LF> Status of compass calibration: a = I:init, R:running, F:failed, C:calibrated
Out from IS15: $PSTOK,,,x.x,*XX<CR><LF> Set compass offset. x.x is offset angle, 0 to 360 degrees
Out from IS15: $PSTOC,*77<CR><LF> Start compass calibration.
