Sun Vector–Based Attitude Determination of Passively Magnetically Stabilized Spacecraft

Abstract: This paper examines the problem of attitude estimation for passively magnetically stabilized spacecraft using only sun-vector measurements. An analytical investigation of local observability is performed in the case where the spacecraft magnetic dipole is constant. This is relevant because for passively stabilized spacecraft using permanent magnets and magnetic hysteresis rods, the hysteresis rod dipole moments are nearly constant at steady state. It is shown that under reasonable assumptions on the Earth's ma… Show more

“…Ideas included performing full attitude determination based on the functional sun sensors only (along the lines of Ref. [12]), and using the star tracker for coarse attitude determination, either directly from tumbling (based on Ref. [13,14]) or after attitude stabilization using momentum transfer algorithms (as described in Ref.…”

“…Attitude determination from vector observations is usually employed in astronautical applications for state estimation and control of spacecrafts [1][2][3]. Commonly, the vector observations are acquired from vector-measurement sensors e.g., Sun sensor, Nadir sensor, magnetometer, star tracker, etc.…”
