lizard said:Better question could be why not 22 satellites, PV2+ have so much interference onboard, DJI needs to assure, the reception is at least somehow working, so the 6 is required in precautionary manner.
See my post there : http://www.phantompilots.com/viewtopic.php?f=27&t=17007
Whole PV2+ GPS reception is actually screwed by the parasitic RF radiation from poorly shielded and poorly designed camera subsystem.
Did you actually also do a test with the camera disconnected? Would it be easy to shield the radiation coming from the camera?
