Reference Point Offsets Packet

The reference point offsets packet can be used to adjust the measurement point that all data is
referenced to. By default all the values of this packet are zero and the measurement point that all
data is referenced to is the centre of the GNSS Compass unit. The primary reference point offset
can be used to adjust the measurement point to a different location on the vehicle. The primary
reference point offset applies to all data output including NMEA etc as well as heave point 1. The
other heave point offsets apply only to heave points 2-4 in the Heave Packet.
