Research on Small Satellite Formation Scheme for Earth Observation Task

摘要

The demand of earth observation data is increasing currently and the demand of observation data accuracy, real-time, and continuity is improving continually. Aiming at this problem, the small satellite formation scheme for earth observation task is researched. The significance of the small satellite formation for earth observation task is analyzed. Based on the summary of small satellite formation, the difficulties and enlightenment about small satellite formation for earth observation task have been drawn. Under earth observation task and multi-constrained conditions, the configuration of small satellite formation, the controller of keeping configuration and the scheme of configuration reconstruction are designed.
