DEAR MODERATORS, PLEASE ADVISE.
,,Repaired" drone is terrible, still same issues, who tests them? Stevie Wonder?
I dont want to keep it anymore, and I dont want to have anything to do with Reapir Centre cowboy technicians.
There are various conditions which can affect GPS signal.
Even if you have multiple satellites visible, signal can be weak for multiple reasons (weather, satellite positions, obstruction of signal etc.).
It is clear from your screen shots that your Spark sees enough satellites but "thinks" that it is not getting strong enough signal to lock in to maintain position. If you tried to fly it in various places, as you said you did, I'd suggest that your Spark has a faulty GPS receiver. What Hannes1 suggested with the magnetic lock, would have impacted your compass and your Spark could have kept switching to ATTI due to compass issues, but should not have affected GPS.
In any case, my bet is that your IMU (and in particular - GPS signal receiver) is faulty. This probably warrants replacement of Spark's motherboard. Weird that this happened to you again with a refurbished Spark. Perhaps you are right about "DJI cowboys" :-)
Good luck!
Mirek
