Question:
My AIS GPS receiver (or transceiver) outputs the vessel’s GPS position as well as incoming AIS messages. Can I use the AIS device to supply Fugawi with the vessel’s position, as well as AIS information?

Solution:
Enable GPS|Settings|Use location information from AIS if you want your own vessel's position to be determined from an AIS receiver rather than from a conventional GPS receiver. Some AIS receivers put out NMEA RMC messages and/or the VMO (own vessel position) messages. These can be used to provide the position, speed and heading for your vessel.

NOTE: if you use the AIS for your position, you will not have any satellite constellation data, which is ordinarily helpful in confirming the quality of the GPS fix. Altitude will also be missing. If you enable GPS|Settings|Use location information from AIS and you also have a conventional GPS receiver attached to Fugawi or are receiving another GPS position via NMEA, then this position will also be used by Fugawi. If there is a discrepancy between the two positions, you may see the GPS icon jumping between these two (or more) locations.
