Hi,  
I’ve 2 different Pixhawk 2.4.8 with corresponding uBlox M8N and I’m trying to build a Quadcopter.  
I’ve uploaded PX4 1.10.1 and done the calibrations without problem.  
When I set Position mode, I get a REJECT POSITION CONTROL error. GPS status is ok (3DFix with 12 satelites).  
If I issue `ekf2 status`, I can see both local and global positions as invalid.

Same problem on both boards/GPS.

Any ideas? How do I troubleshoot it?

Thanks
