I've had my P3A for a few weeks and having great fun with it. However I took it out yesterday evening a couple of miles from where I usually fly and there were no GPS satellites detected. Big open forest expanse, no satellites at all (in fact the GPS icon on DJI Go was greyed out). Was a bit frustrating and so came home and again no satellites. I've recalibrated the compass and IMU and re-installed DJI Go, but it just sits their flashing 2 green blinks (no GPS according to the manual) saying Safe to Fly (No GPS). Obviously I don't fancy it blowing away so I'm not going to fly it too far without GPS. I did have a bit of a crash at the weekend, but it was flying perfectly fine on Tuesday, took it up with full GPS lock and nothing has happened to it between Tuesday morning and Wednesday afternoon. Any thoughts/recommendations?
