Last saturday i experienced GPS problems again, listed below, also compass errors even far away from metalic objects, i got tired of all this and i will be sticking with my good and reliable Pixhawk 1 and my Pixhawk 2.1.
GPS taking too long to lock, despite it is a M8N Ublox on board the Navio+.
Under cloudy skyies, it takes more then 20 minutes to show 5 or 6 sats.
Last flight, i had 13 sats and in mid flight it lowered to 5 sats, HDOP went to 3.5 and came back to 13 sats.
Error compass variance is constant, every day, it is annoying. Tried compass calibration many times.
Magnetic field messages even far away from metalic objects.
Maybe a external GPS unit would help but i need the UART for OSD and USB for telemetry and i don`t want to work with USB settings. Why do we need an EMLID GPS antenna? It should work in first place.
I am giving up with this project. Sticking with the Pixhawks. I will never look back.
