Abstract

The invention provides a satellite measurement and control scheduling method and system based on clustering, tasks are divided into K classes according to task characteristics, the close relation between the tasks is evaluated, similar tasks are close as far as possible, different tasks are far as far as possible, and when a genetic algorithm based on clustering is used for crossover and variation of populations, the clustering algorithm is used for clustering, so that the clustering efficiency is improved. Two different types of individuals are subjected to crossover variation, so that the balance of global search and local search is realized, a solution with higher quality can be obtained, and the problem of sequence dependence is well solved. Experiments show that the same optimization effect can be achieved in about one third of the time of a knowledge-based genetic algorithm by using the method disclosed by the invention.

Description

technical field [0001] The invention belongs to the field of satellite task planning, in particular to a cluster-based satellite measurement and control scheduling method and system. Background technique [0002] In recent years, with the rapid development of space technology, satellites play an increasingly indispensable role as a space platform that can be applied in many fields. Satellites are used to complete various types of tasks such as target observation, navigation and positioning, and communication transmission, depending on the user's mission requirements. No matter what kind of task the satellite needs to perform, the satellite ground station needs to transmit the task in the form of instructions by the uplink directly or indirectly (transmitting to the relay satellite first). The process that the ground station uploads tasks and action instructions to the satellite and obtains the operating status of the satellite is called satellite measurement and control. T...
