hi
I need a little info. After moving the FC from one frame to another (identical) and after a reset, the FC Cube Black always gives me the same error: “need 3D fix” even if the acquired satellites are 17
The system is a Cube Black with Herelink and GPS Here2 (connected in Can). I have disabled compasses 1 and 2 (internal) and I have active only 3 (external) and HDOP 0,7 (limit fix at 2,5)
I left the system in the middle of a field for 1 hour to give time to enumerate the constellations and calibrated the compass 3 several times but the problem remains
another small detail … if I enable compass 1 (internal) and 3 (external) the problem disappears but the UAV works very badly … hovering with “toilet” effect and deviation of course in a straight way … etc ( probably suffers from some EM field due to the DB that is in the area and it is for this reason that I want to use only the external one)
For all of the above, do you have any advice on how to solve the “need 3D fix” problem?
