Hi, I regularly upload flight data to healthydrones.com to analyze it. There is one set of data displayed that I can't seem to reference properly. On the notifications tab I sometimes see items like: Mode changed to 127 Mode changed to GPS Atti See below: I was flying in P-GPS mode and never changed it during the flight (It was green and safe-to-Fly when I took off). The P3 manual states that there are 2 flight states under P-Mode: P-Mode (Positioning): P-Mode works best when the GPS signal is strong. One of its two states will be selected by the aircraft automatically depending on GPS signal strength. P-GPS: GPS is available. The aircraft uses GPS for positioning. P-ATTI: GPS is not available. The aircraft only uses its barometer to maintain altitude. Neither of these 2 map to what healthydrones.com shows. Also the GPS data seemed to show I had good signal when I left home all the way though landing. Can somebody give me insight into how to interpret these notifications? Something is obviously happening and I would like to understand what it is. Thanks.
