Abstract:

In order to detect maneuvers of the uncooperative space objects, the universal detection algorithms and procedures are presented innovatively in this paper. The different thrust dynamic models are described in details, based on which the detection strategies are provided, including space-based and ground-based observations simulation strategies, software platform of data processing, detection algorithms and procedures for impulse thrust, high and low finite thrust, and accuracy evaluation strategies. The simulation analyses are made on different thrust maneuvers detection and orbit accuracy recovery based on the space-based and ground-based simulation observations. The work confirms that the detection method in the article can satisfy most of tasks for uncooperative objects detection, and provides a salutary lesson for engineering tasks.

Key words: Maneuvers detection, Uncooperative objects, Impulse thrust, High finite thrust, Low finite thrust, Space-based and ground-based observations
