Abstract

The invention provides a satellite-borne general description method and system for a multi-satellite multi-mode maneuvering imaging model, and the method comprises the steps: a classification step: determining the imaging modes of all types of member satellites in a satellite cluster, and dividing different imaging modes into two types according to maneuvering dimensions; a constraint extraction step: abstractly extracting the constraints of the member satellites in the two classes, and integrating the constraints by the central satellite; a maneuvering time confirmation step of defining maneuvering time of various member satellites in the satellite cluster in a single rolling shaft maneuvering mode; a polynomial fitting step: performing polynomial fitting on the attitude maneuver angle time in the single rolling shaft maneuver mode; a defining step: defining different imaging process time periods in a two-axis maneuvering mode; and a planning control step: forming a fluence packet through a description method of a general imaging model to realize planning control of a star cluster task. And the planning efficiency of the multi-satellite cooperative work task is improved, so that all member satellites in the star cluster system can exert various maximum efficiencies.

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...
