Abstract

The invention discloses a satellite ground observation system task deduplication method based on knowledge evaluation. The satellite ground observation system task deduplication method comprises the steps that knowledge value evaluation is conducted on each satellite, and when task conflicts exist in observable time windows of the multiple satellites, task time duplication eliminating is performedaccording to knowledge value evaluation scores of the satellites. According to the method, a satellite ground observation system task deduplication method based on knowledge evaluation is realized; knowledge value scores are given to all satellites, a traditional algorithm is optimized to serve as a voucher for task deduplication according to the maximum task execution time, and the maximum observation value can be achieved for an observation user when multiple satellites observe task conflicts.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to a task deduplication method for a satellite ground observation system based on knowledge evaluation. Background technique [0002] In recent years, aerospace technology has gradually developed towards private commercial use. Various scientific research institutes and enterprises have planned to launch a large number of commercial satellites, and the number of spacecraft in orbit has increased rapidly from thousands to hundreds of thousands. The problem of mission planning for ground stations under constrained conditions gradually emerges. The optimization of the mission planning algorithm of the satellite ground station is also imperative. [0003] Due to the objective fact that the ground observation station has a time window for satellite observation, when the ground observation station observes multiple satellites, the time windows of multiple satellite observation ...
