Application of geomagnetic sensors in drones

UAV flight requires an Attitude and Heading Reference System (AHRS). The accelerometer and gyroscope can estimate the roll and pitch of the aircraft. However, yaw cannot be accurately obtained through these two, so a geomagnetic sensor is required. The geomagnetic sensor mainly calculates the angle between the aircraft and magnetic north based on the geomagnetic vector.

Industrial-grade drones can be used in a wide range of fields, including scientific research (climate, topography, ecology, minerals), environmental monitoring, infrastructure inspections, disaster relief and epidemic prevention (mountain disasters, shipwrecks, air crash searches, spraying disinfectants, and mass gatherings) warning), agriculture, forestry, fishery and animal husbandry management (spraying pesticides, field or orchard inspections), spatial information measurement, media communication, telecommunications services, logistics home delivery, entertainment activities, etc.

When the drone is flying, it has high requirements for the accuracy of the heading and orientation, so it has high requirements for noise. The motor on the machine body is easily close to high-voltage wires in the environment when rotating and flying, which is the main source of magnetic interference. Therefore, the requirements for tolerance to magnetic field interference and data output rate are relatively high to reduce the impact of such interference.
