Hello,

can some one please help my with this:

I try changing flight mode to “guided” but I get a message “flight mode change failed”. My setup looks ok for me. GPS connected, rtk Fixed, manual operation with my remote works.

There is a message “unhealthy GPS signal”. However I have a perfect view and good GPS position.

Can anyone help me here ?

thanks
Konrad

A good GPS position, but probably a too low update rate. The minimum update rate is 5Hz.
Reduce the amount of GNSS constellations to fix this.

Thank you for this hit.

Meanwhile I could fix this myself. Maybe someone has similar issues: I use the UM982 and according to the manual heading info is sent via the UNIHEADINGA command but this seams not to be processed by the Pixhawk. So I changes this to GPTHS and now it works.
