Yes, that's one approach. Be sure to consider: - surveyed positions of your fixed antennas - number of mobile devices - size of vessel - what happens under marginal signal conditions (do receivers claim to have a good quality fix but at the wrong position) - error detection/correction in the app - loop detection, so that this app does not use its own output like the output of a receiver. ...
Perhaps without the feeding-back path it would become simpler. gpsd provides data from individual devices, 'aggregate_gpsd' combines it into a new feed. Keeping the protocol format. Clients can then connect to aggregate_gpsd instead, should they want to. Cheers, Håkan
web search for "gps attitude sensor" will give some hints on the current state of the art.
