there is only a handfull companies, none of the "usual" big players, supporting rotating masts, but there are nice new sensors from airmarine and Maretron.
Both deliver NMEA sentences about wind data, the airmarine comes even with build-in
GPS and
compass. But this data must be corrected for the mast rotation, it could be done by a PC, but this is to much power input in the long run and might confuse the navigationPC when there are multiple NMEA processes running same time.
a small single board computer, even a 8088, something small and simple in a blackbox, should receive heading data from the mast and from ship
compass and correct vor the rotation and then return the corrected wind direction and speed to the NMeA bus.
anyone who assembled like that alread?
Or who is capable of heliping out?
I and many others woul be happy to find help.
