Observability Analysis and Design of Two Nested Filters for the Satellite Attitude Estimation with Magnetometer-Only

This study aims to propose a scenario for determining the attitude of a nano-satellite with only a magnetometer in the case of temporal failure or faults in other sensors of attitude determination subsystem. For the sake of this matter, two nested filters are employed. The first filter estimates the magnetic field derivative by an extended Kalman filter (EKF). This information is applied along wit...
