Abstract

The invention relates to a sky scanning multiple-objective task programming method for a space astronomical satellite. The method comprises the first step of grid division and numbering of a celestial sphere, the second step of processing of a visible window and constraint conditions, the third step of programming and modeling of multiple-objective tasks, the fourth step of resolving processing of a multiple-objective and multiple-constraint-condition programming model. According to the sky scanning multiple-objective task programming method for the space astronomical satellite, planet energy, storage and ground data transmission constraints are comprehensively considered, multiple-objective programming problem modeling is conducted from the aspects of the scientific detection requirement and the project implementation requirement, and a solution algorithm is provided to lower the time of conflict resolution and space complexity.

Description

technical field

[0001] The invention relates to the field of satellite resource task planning and dispatching, in particular to a space astronomical satellite sky survey scan multi-target task planning method. Background technique

[0002] Space astronomical observations refer to the astronomical observations carried out from tens of kilometers above the ground to the space beyond the earth's atmosphere. It is an important way for human beings to accurately detect cosmic phenomena, reveal the laws of the universe, and promote their own progress.

[0003] As an important guarantee for the efficient and smooth implementation of satellite operations and detection tasks, the research on satellite mission scheduling and planning strategies is of great significance for rationally arranging detection plans, optimizing satellite-ground resources, and maximizing the realization of observation goals. Compared with traditional earth observation satellite missions, space astronomy satel...
