Magnetometer calibration errors can have significant consequences on UAV navigation, primarily affecting the accuracy of heading and orientation estimation. A magnetometer is a sensor that measures the strength and direction of the Earth's magnetic field. UAVs use magnetometers to determine their heading (direction of travel) and orientation in space. Accurate magnetometer readings are crucial for stable and precise flight, especially in GPS-denied environments or when relying on autonomous navigation. If the magnetometer is not properly calibrated, it can provide inaccurate heading information to the flight controller. This can lead to several problems. Firstly, it can cause inaccurate heading estimation, leading the UAV to drift off course or fly in the ....
