This section describes how to calibrate the internal compass in the aircraft.
The aircraft’s compass is calibrated at the factory and typically does not need to be
re-calibrated. Compass calibration may be necessary if significant hardware
changes have been made or if metal has been added to or removed from the
aircraft.
Indications that the compass may require calibration include:
● Toilet bowling (circling during hover)
● Veering off-path when attempting to fly straight.
IMPORTANT: Do not calibrate the compasses near any metallic or magnetic field
producing object (computers, cell phones, metal desks, power supplies, etc.) or
incorrect calibration will occur.
Metal is not always obvious! Do not calibrate on top of an office table (often
contains metal bars) or next to an aircraft. Calibration can even be affected if
you're standing on a slab of concrete with uneven distribution of rebar.
Compass calibration is accomplished by using either QGroudControl or Mission Planner. Click
