The present invention provides a spaceborne general description method and system for a multi-satellite multi-mode maneuverable imaging model, comprising: a classification step: clarifying the imaging modes of various member satellites in the cluster, and dividing different imaging modes into two categories according to the maneuvering dimension; Constraint extraction step: After abstracting and refining the constraints of each member satellite in the two categories, they are integrated and processed by the central star; maneuver time confirmation step: in the single-rolling axis maneuver mode, specify the maneuver time of each member satellite in the cluster; Synthesis step: polynomial fitting of attitude maneuver angle time in single-axis maneuvering mode; definition step: define different imaging process periods in two-axis maneuvering mode; planning control step: form note Counting packets to realize the planning and control of cluster missions. Improve the planning efficiency of multi-satellite collaborative work tasks, so that each member star in the star cluster system can exert its maximum performance.
Description
technical field [0001] The present invention relates to the field of multi-spacecraft collaborative mission planning, in particular to a spaceborne general description method and system for a multi-satellite multi-mode maneuvering imaging model. Background technique [0002] With the continuous increase in the number of satellites in orbit and the continuous upgrading of satellite capability requirements, large-scale networked satellites and formation satellites have emerged, and new requirements for multi-satellite collaboration and inter-satellite interconnection have been put forward. [0003] The star cluster system is mainly composed of intelligent satellites (central star) and multiple imaging stars (member stars). The central star and member stars use the multi-star collaborative mission planning system on the central star to centrally integrate and deploy the data of each member star. Various payload imaging tasks. The multi-satellite coordination system has its own...
