Hi Frank
I checked your log 005 and I see what you are talking about.
The first flight was with hacc 100m - manual.
The second flight you had about 2.2m hacc which is a terrible value.
Most spikes occur whan you have RC input.
Then you switch to PH and you have spikes with no RC input - that's because the FC is navigating now.
To me it looks more like some mistuning and/or EMI than GPS problems.
Can you describe your craft.
Esc's, Esc hookup, motors, props, AUW, protocols used ect. Please post some pics of the craft. I am especially interested in the powerlines and PWM cables.
Cheers
Christof
