Hi,
After completing the test manual flying of my agriculture drone with empty payload, I did the log analysis, and found compass fail error:
Test: Compass = FAIL- Large change in mag_field (82.34%)
For Drone I am using:
Battery is placed on the top cover of fuselage. and from battery Gps position is 15 cm above).
Note: Before my test flying, I completed the Compass calibration process.
My queries are -
Why Compass is showing that much of error ( Compass = FAIL- Large change in mag_field (82.34%))?
Is UAVCAN GNSS contain only External compass?
Is there internal compass in EDGE.
How to solve magnetic compass error?
Thanks
Hi @DTLPRATEEK ,
I think that this thread looks similar to yours:
After completing the test manual flying of my agriculture drone with empty payload, I did the log analysis, and found compass fail error:
Test: Compass = FAIL- Large change in mag_field (82.34%)
For Drone I am using:
P 80 100KV T motor
Flame 80A ESC
30 x 10.5 Propeller
12s12p 44.4V 34.8Ah Li-ion battery (Dimension - 25x25x7 cm , 7cm thickness)
Flight controller - EDGE
GPS - UAVCAN GNSS
Battery is placed on the top cover of fuselage. and from battery Gps position is 15 cm above).
Note: Befo…
There’re also some useful tips on how to prevent EM field effect and try to get rid of the error.
The solution is clearly stated in the video, as far as I am concerned:
All power-wires must run in parallel with its own +/- counterpart.
Twist/braid your wires where possible.
use shielded wires for signal-transmission.
place compass away for power-wires.
if a buzzer is installed, place that away from the compass.

Compass error (Magnetic interference) is obviously present because as i m working at a place where there is so much aluminium work is going on and also the metal noise also induces the interference according to be but if we work at isolated place then does it makes a difference ?
It’s hard to say without tests.
Do you have an opportunity to make one outside this place?
