Bad GPS Health only with APM


im just trying out the Navio+, and it seems like i got a problem with the GPS unit. If i dont start APM and only use the GPS with the U-Blox Software i get a relly fast fix with 3m accuracy. But when I start APM i cant manage to get a fix.

First i thought it might be a problem with the soldered GPS antenna, but if it works well in u-center?

Did any of u experience a similar problem? I am not using a Pi-Cam also i dont use a 4G Module. I only use a 433Mhz 3DR-Antenna and my normal Transmitter setup.

Thanks for your help.


Could you please provide a screenshot with satellite levels from U-center?
