Hello everyone,
I’m trying to take off using my GCS in GUIDED_NOGPS, but whenever I hit the take-off button the following error appears:
[ERROR] [1700190458.189110081]: FCU: PreArm: AHRS: EK3 sources require RangeFinder
Now, I’m using a Vicon system to feed the data to the QUAV and the attitude is correctly reflected in my GCS. I followed all the steps in the ArduPilot documentation including setting the following parameters:
EK3_ENABLE=1
EK2_ENABLE=0
AHRS_EKF_TYPE=3
EK3_GPS_TYPE=0
EK3_MAG_CAL=5
EK3_ALT_SOURCE=2 (Apparently this one is now called EK3_SRC1_POSZ)
GPS_TYPE=14
GPS_DELAY_MS=50
COMPASS_USE=0
COMPASS_USE2=0
COMPASS_USE3=0
Additionally, I’m using the Ardupilot version 4.4.1 (which is the newest the navio2 repo allows me to download). I also tried to take off using MAVProxy in case my GCS was the problem, but the same error message appeared.
I would appreciate any help on this matter.
