External Disturbances Rejection for Vector Field Sensors in Attitude and Heading Reference Systems [PDF]
Micromachines, 2020 The attitude and heading reference system (AHRS), which consists of tri-axial magnetometer, accelerometer, and gyroscope, has been widely adopted for three-dimensional attitude determination in recent years. It provides an economical means of passive navigation that only relies on gravity and geomagnetic fields. However, despite the advantages of small
