Approach to study satellite attitude determination algorithms

• Approach to the study of Kalman filter features is proposed.
• The approach is applied to study Chibis-M attitude determination algorithm.
• Calculated accuracy of Kalman filter is compared with in-flight results.

The Kalman filter accuracy study method is proposed. Application of the method is demonstrated by a satellite attitude determination algorithm which uses sun-sensor and magnetometer measurements. The algorithm was implemented on board of a microsatellite Chibis-M. The attitude determination algorithm study method validated using in-flight measurements.
