Here at Heliguy, we have many customers confused about the compass calibration procedure on DJI Phantom quadcopters. We hope the following information helps you up in the air faster.
IMPORTANT: You must perform the Compass Calibration procedures prior to the first flight.
The DJI compass is very sensitive to electromagnetic interference which causes abnormal compass data and leads to poor flight performance or even flight failure. Regular calibration of the compass enables the compass to perform at its optimal level.
- （1）DO NOT calibrate your compass where there is a possibility for the existence of strong magnetic interference such as magnetite, parking structures, and steel reinforcement underground.
- （2）DO NOT carry ferromagnetic materials with you during calibration such as keys or cellular phones.
- （3）Compass Calibration is very important; otherwise the flight control system will work abnormally.
Please carry out the calibrating procedures in the flight field before flight. Once it has been carried out, the Phantom will still take some time before it finds satellite sufficient to support GPS flight. It is safe to take off in GPS mode once the Phantom has displayed the rapid green LED light sequence.
This flow chart details what you need to do to calibrate the compass on your DJI Phantom Quadcopter and what to do if the compass calibration fails.
