If you have a faulty compass module, then you might wonder how to calibrate compass on Phantom 4. Fortunately, this is a simple process and does not need to be repeated before every flight. Depending on your circumstances, you might not need to calibrate it even once during one flight. If you do, you should find a location with wide open space, away from overhead power lines, concrete structures, and drainage pipes. This should prevent your phantom from flying in places that are not ideal for calibrating. This method is also suitable for indoor use and can be performed on any surface, whether it is hard or soft.

You’ve just received a compass warning message on your Phantom 4, but how can you fix it? There are a few ways to fix the problem. First, check whether your compass module is faulty. If it is, you may have a faulty controller board. If not, try to replace it. Fortunately, it’s relatively easy to do. You can check your compass module using the DJI Go app or the advanced quadcopter.
A faulty compass module can make your flight unstable. This happens because the flight controller cannot determine the declination and deviation of the location. The global declination model in the firmware is responsible for this, and taking off in an area with a significant magnetic deviation will likely result in a very unstable flight. When your compass data is inaccurate, the Phantom will notify you by flashing red and yellow lights. Once you’ve resolved the compass error, you can fly your Phantom again.
Besides causing flight instability, it’s possible to damage your compass module by putting it near magnets. You should replace your compass module to prevent your Phantom 4 from performing strange behaviors and losing control. To ensure proper flight performance, you should also make sure your compass module is calibrated, a process that should be easy to do on your own. Luckily, you’ll be able to use the GPS module as well, since it has a built-in magnetic field sensor.
The compass module is located on the controller board. There’s a white rubber gasket that fits over the opening where the compass wiring goes. Once you’ve removed the gasket, you can unsolder the compass module with a screwdriver. Once the compass module is removed, you’ll need to replace the four purple connectors on the board. You can even use a flat screwdriver blade to remove the connector from the board.
