Compass calibration.
As the basic model, Topodrone DJI Matrice 200 V2 L1/L2 RTK/PPK (+X4S) needs the compass
calibration (CC) each time you move to the new location
. CC helps your drone to adapt to local magnetic
field lines. During CC, accelerometer and compass makes two rotations in different
axes. After that, drone makes adjustment between values of each sensors. To make
correct CC follow next steps:
1.
CC makes directly before flight at the open outdoor area. Making CC
indoor is useless
2.
It is allowed to make DJI M200 V2 compass calibration when the DJI X4S
gimbal is removed.
3.
Turn on the drone and RC, insert and plug the mobile device.
4.
Make sure, there are no large metal constructions or magnetic fields sources
in 50 meters.
5.
Enter drone into CC mode. At least there are two ways:
a)
In the DJI Pilot app open MC Settings / Advanced settings / Sensors state / Compass /
Calibrate compass / OK
b)
At the front left side of RC, rapidly move the slider to S and A
positions not less than 4 times.
6.
Ensure that rear LEDs of the drone lights solid yellow.
7.
Put RC to the ground and take the drone with both hands. Hold drone
for it’s arms horizontally. Do not change the orientation of the drone!
8.
Rotate drone to the left side (counter-clock wise) in 380 degrees (a bit
more than 360 degrees). Stop when the rear LEDs will change color
from solid yellow to solid green.
9.
Change orientation of the drone, turning it in 90 degrees in a
longitudinal axis.
10.
Rotate drone to the left side (counter-clock wise) in 380 degrees (a
bit more than 360 degrees). Stop when the rear LEDs will change
color from solid green to blinking green.
11.
If using 5a way entering CC mode, turn the Flight Mode slider to
P (central position). This is especially important!
12.
Compass calibration now is complete.
Before and after CC you can check the value of magnetic interference in
the DJI Go Pilot App – it should be at the green zone after CC. If the app notice
you compass calibration failed (rear LEDs blinks red rapidly) – recalibrate
compass at another place nearby.
Notice 1: no magnetic or ferromagnetic objects on the body of pilot are
allowed. For example: massive jewelry, metal inserts or magnets in the end of the
iPad tablet etc. If you have some of these objects, even after successful CC, your
drone will have “Compass Error” after taking off.
Notice 2: CC increase flight stability of the drone during the flight. But compass error can appear even after
absolutely correct calibration. It usually caused by different external interferences such are metal objects, large
antennas, electricity transmission lines (ETL).
