Hi, I am trying to fix some DJI Spark drones with bad GPS boards, which cause
following error - Navigation System Error - check redundancy state, same error
is when GPS board is disconnected from main board.
Serial output console show only garbage at all standard baud rates - that mean
communication is garbage or is encrypted, but more likely boards are dead
for unknown reason.
Does anyone have experience, what could be bad with these GPS boards ?
All were involved in a crash, one have cracked GPS antenna. No other
visible damage.
There is strange metal object near GPS antenna and metal shielding -
is this a battery ? There is + mark on top, but meter show no voltage.
Of course one solution is to replace GPS boards - but I want to know
what is wrong with these modules, and if possible, fix it.
