GPS & Compass Calibration
If the Compass Module is not used, you can skip this step.
The GPS module has a built-in magnetic field sensor for measuring the geomagnetic field, which is not the same in
different areas. The GPS module will not work unless the Compass Module has been connected. Make sure the
Compass Module connections are correct.
Please always keep the compass module away from the magnet. If this situation occurs please change the compass
module before flying. Otherwise it may damage the compass module and lead the aircraft to work abnormally or even
be out of control.
Calibrate the compass before the first flight or when flying in a different area. Make sure to keep away from
ferromagnetic substance and other electronic equipment when calibrating or flying. If you keep having calibration
failure, it might suggest that there is magnetic interference or other ferromagnetic substance, please avoid flying in this
area.
If you have calibration failure or the LED blinks red and yellow lights alternately ( ), please connect to
the Assistant Software, select the “Tools” tab and follow the tips of the “IMU Calibration” to do operation.
1. Quickly switch the control mode switch from
ATTI. Mode
to
GPS ATTI.
Mode
and back to
ATTI. Mode
for 6 to 10 times, The LED indicator will turn
to constantly yellow.
2. Rotate your aircraft around the horizontal axis (about 360
o
) until the LED
changes to constant green, and then go to the next step.
3. Hold your aircraft vertically and rotate it (its nose is downward) around the
vertical axis (about 360
o
) until the LED turns off, meaning the calibration is
finished.
4. If the calibration was successful, calibration mode will exit automatically. If the
calibration has failed, the LED keeps flashing quickly Red. Switch the control
mode switch one time to cancel the calibration, and then re-start from step 1.
