I tried .otherNavigation and .other Also, it is not snapping to roads, at all. It is just that when the ship moves slowly, it does not really update the reported position, insteads it stays around the current position for a while and later makes a big jump to a new area where it resides then. The behaviour seems to occur less often if the ship is travelling faster (e.g. downstream). I parsed the internal locationd logs for GNSS NMEA messages and resolved positions and related them. The NMEA reported raw positions are plotted in blue, the resolved positions are plotted as green circles with their radius being the reported accuracy, and there are faint orange arrows pointing from NMEA positions to the afterwards resolved positions which are then reported to the apps.
