This video was taken last weekend during tests of latest changes implemented in iNav, as well as new GPS module Beitian BN-880 I shortly described here.
Mission plan:

  • Take off in Angle mode,
  • Engage 3D Position Hold
  • Fly away 100m
  • Return to Position Hold
  • Engage Return To Home mode

Summary:

  • Beitian BN-880 performed well. Quadcopter returned home with 1m accuracy. Constant fix on 15 sats all the time and HDOP at 1.2
  • No problems with magnetometer inside GPS module
  • No bigger problems during whole mission. I still have to work on yaw behavior. At the moment FP-PID and linear mixer from Betaflight can cause some strange yaw behavior on bigger quads. Fix should be available soon
