10. Compass offsets too high
The cause of the problem:
The offset value of the main compass (i.e. sqrt(x^2+y^2+z^2)) is
greater than 500, and this will be prompted. Generally, there are magnetic objects (motors,
screws,battery) near the flight controller or GPS, or the environment has strong magnetic
interference.
Solution: Please remove the interference and power on again, install the flight controller or
GPS in another location, and re-calibrate.
11. Check mag field
The cause of the problem:
If you are indoors, or change to a different environment, or there
is magnetic interference nearby, this error may be prompted.
Solution:
If you change the environment, just do the calibration again. If you are indoors or
there is an interference source, just leave the interference source.
12. GPS Glitch/ Need 3D Fix
The cause of the problem:
If the GPS is not positioned successfully or there is no GPS. And
the flight mode that requires GPS is used or the electronic fence is activated, these two error
messages will be prompted.
Solution: If GPS is not installed or flying indoors, please switch to the flight mode that does
not require GPS and wait for GPS to be positioned by 3D FIX.
13. Bad velocity
Cause of the problem:
The problem may be that the moving speed is too fast, or the
accelerometer is not properly calibrated, or the GPS refresh rate is lower than 5HZ.
Solution: Wait for the GPS satellites to lock more. HDOP is less than 1.5.
14. High GPS HDOP
The cause of the problem:
The satellite positioning accuracy HDOP is too high, which is
generally caused by insufficient satellites.
Solution: Put it in an outdoor unobstructed environment. Wait for more satellites to lock on
before flying.
15. INS not calibrated
The cause of the problem:
the accelerometer is not calibrated, or the calibration is incorrect.
Solution:
Re-calibrate the accelerometer.
16. Accels not healthy
