I has been watching the AISradar targets for some minutes. My testing is done indoors with bad GPS coverage where the GPS position fix is coming and going. When loosing GPS fix, the AIRradar targets will have random direction even if the same targets on the map is stable and correct, so it seems that the problem is related to GPS compass
course / GPS position on my desktop
system not always have a GPS fix. But even so, if the AIS targets show on the AIS radar, they should display in the same direction ad on the map as long as both the map and AIS radar is set to North up.
