Description

technical field [0001] The invention belongs to the technical field of satellite mission planning, and in particular relates to an evaluation method and device for a multi-satellite earth observation mission planning algorithm. Background technique [0002] Satellite mission planning mainly solves how to effectively allocate and schedule multiple satellite resources, specify satellite observation plans, and maximize the completion of tasks submitted by users. The results directly affect the task execution effect of the earth observation satellite system. At the beginning of the development of earth observation satellites, due to the limited satellite load capacity and relatively few user tasks, the observation time and observation angle of the tasks were relatively fixed, the satellite management and control were relatively simple, and the problem of mission planning was not prominent. However, with the development of earth observation satellite technology and the increase i...
