Bug report Issue details
I am experiencing an issue with the configuration of my flight controller and RTK system. The copter only arms in Stabilize mode and fails to switch to other flight modes like AltHold with the error: "Mode change to ALT_HOLD failed: need alt estimate."
Version ArduPilot 4.6 Dev
Platform [ ] All [ ] AntennaTracker [X] Copter [ ] Plane [ ] Rover [ ] Submarine
Airframe type Quadcopter
Hardware type Matek H743 Slim V3
RTK System H-RTK Mosaic-H (Dual Antenna Heading) from Holybro
Issue details
Reset all settings to default values. Applied the recommended settings from the Holybro documentation (https://docs.holybro.com/gps-and-rtk-system/h-rtk-mosaic-h/setup-and-getting-started-ardupilot). Verified correct installation and functionality of the barometer and GPS. Checked EKF settings: EK3_ALT_SOURCE = 0 (Barometer) EK3_HGT_SOURCE = 0 (Barometer) EK3_SRC1_YAW = 2 (GPS), but also tried 1 (Compass) to avoid errors. The problem persists even after resetting and reapplying all settings. It appears that the system is unable to obtain a reliable altitude estimate outside of Stabilize mode.
