GPS Compass

[mgrouch]

To achieve accuracy it would require 2 multi band GPS antennas (not usual ones)
with support of up to L5 GPS bands and multiple GNSS systems (GPS, Galileo, GLONAS, etc)

GPS receiver needs to be able to send raw gps data (again not average GPS receiver chip) to RTK Library

RTK library seems does support moving base and a rover combination of receivers,
but I do not think it’s Kalman method implementation would take advantage of fusion of data from
different bands

Overall looks complicated and not too cheap for hardware with no guaranteed success.
