  • Regarding GPS accuracy:

    If you are able to set up a pair of receivers (one on UAV and one static/ground unit) you can use RTK - where the static/ground one sends a correction feed (~120Byte/s) to the rover. With quality receivers you can get sub-centmeter accuracy even with L1 only receiver.

    Of course we're all on a tight/personal budget and can't afford the 'Novatel' units, so it's good to know there is an open source solution:
