I would really like to know if anyone can figure this one out. I was at a cabin in a federal forest in upper Wisconsin. Absolutely nothing around for ten miles or more, all trees and a river. No electricity here, just a radio tower for use in emergencies on the cabin. It was not being used or turned on. I went straight up to just under 400ft a few minutes into the flight I was not even 200ft away I did get a high wind warning. I started to bring the magic down to around 225ft and stayed under 200ft from home base. Out of nowhere I lost all satellites and got a compass error. Mavic started flying backwards across the river and I had no controls at all. I switched to sport mode and immediately got responsive controls. I was able to land at home point manually but was scared to take it up any distance again. I did check everything over and put it back up to 125ft in elevation and everything seemed fine but I was afraid to fly away from home point. Any ideas on what causes you to totally lose satellite signal with absolutely nothing around? Also I dont know how to upload my flight logs?
