Hello I'm starting on Litchi software. After having pre set a WayPoints mission on Litchi - Hub, I observe a GPS positioning problem once arrived on the perimeter of flyover. Indeed, once arrived at the scene I download the mission then I ask Litchi to run it : to my surprise, the drone is more than 100 meters away to fetch the WayPoint 1 ! It is as if the GPS was distorted. Here are my equipment and software versions: - Phantom 3 Professional, DJI Go 2.7.2, Remote controller 1.6.0 - firmware 8.1.80; - Litchi 3.3.0; - smartphone Samsung S6 Edge+ acting as a hotspot for the tablet Samsung Tab S2 connected to the Remote Controller; - on the field, the GPS position ans the localisation on the map, for Home, is perfectly accurate. Can you help me to correct the offset between GPS coordinates in the pre set mission and the reality on the ground? Thank you.
