I have 2 identical F9P GPS module working as dual GPS for AC4.0 and I have some questions, hope that someone could help:
- How to verify/check that how much better dual GPS comparing to single GPS. My idea is setting waypoint and analyze the dataflash log. However, I expected GPSB (yellow) will appear but it did not:
- If one of the GPS gets wrong (cable connection, hardware problem…) or be glitched, how Ardupilot will behave? (continue to calculate blending GPS by doing the weighted average or ignore the bad one)
Thanks in advance!
