Help Diagnose GPS Glitch


I was in loiter with my Pixhawk powered hex doing some testing in the driveway. HDOP was not very good for the flight. I knew that but cautiously was in loiter anyway.

Towards the end of the flight the hex drifted suddenly. I flipped back into manual and landed. Reviewing the log there was an instant that all satellites were lost and I have infinite HDOP.

I have been through my machine. Every connection looks good. Maybe I should have not loitered with HDOP >2, but that doesn’t explain why it would lose all satellites. What can I do to diagnose this brief glitch?

Any insight is greatly appreciated!
