Change to “ALT_HOLD”, and managed to arm. Change back to “LOITER”, same result: " Prearm: “GPS (2) YAW NOT AVILABLE”. Restarted the drone, and again got GPS1 3D FIX and GPS2 RTK FIX. Shows 90 degrees of to the left. Able to arm in “STABILIZE”, but not “ALT_HOLD” or “LOITER”. After 3 min the GPS1 changed to 3D DGPS. for 1. I don't believe this is the best scenario. As Bad GPS Health is to do with hdop and sat count, and does not fit under the 3d fix/no fix solution. 2a. I will see if I can add individual sensor health output.
Thanks for this hint. Since I loaded ArduCopter V4.1.1-rc1 (bc6b31bc) on my matek H743, GPS was not detected any more. I set GPS_DRV_OPTIONS = 5 and GPS was immediately detected with a 3D-Fix - even without a restart of the FC. In mission planner I got the following messages: 28.10.2021 17:17:36 : u-blox 1 HW: 00080000 SW: ROM CORE 3.01 (107888)
mission planner shows a gps no fix sign. No Fix say a GPS is detected, but position is not. As GPS chip is on the Navio2, even without good GPS signal, the No Fix msg is the minimum. You have to check the seating of the GPS antenna plug:
Recently ordered a GPS + compass module From bangood.I have connected the GPS pins in proper position and the compass is working excellent but I can’t get any satellite in my mission planner. It also shows the GPS no fi…
Just do MP–>Flight Plan–>MP Tool–>Prefetch by doing Alt+select area (while PC is connected to Internet). This will save the map in C:\programdata\mission planner\gmapcache. Now take the same laptop/PC to selected area (where there is no internet). Open Laptop/MP and connect to Pixhawk via Mavlink. MP will automatically load gmapcache map
