Abstract

The invention provides a method for distributing satellite receiving tasks. The method comprises the steps of decomposing the satellite receiving task planning problem by the divide-and-conquer method; decomposing the satellite data receiving task problem under a large task quantity into a plurality of sub-problems under a small task quantity; optimally configuring a ground receiving resource of each satellite data receiving task of each conflict task set by the genetic algorithm by considering the satellite-earth resource limitation, so as to reach the purpose of fully utilizing the ground receiving resource. According to the method, the parallel strategy of dividing and conquering is carried out to greatly increase the satellite receiving task planning efficiency; in addition, the genetic algorithm is performed for the satellite receiving task planning problem under each small task quantity, and therefore, the ground receiving resource is quickly and fully distributed, and the optimal satellite receiving task planning scheme can be obtained. According to the method, the automatic mode is performed, so that the brain power of operators can be relieved, and the planning efficiency and the capacity of responding to the emergency task can be greatly increased.

Description

technical field [0001] The invention relates to the field of aerospace ground reception, and more particularly to a satellite reception task assignment method. Background technique [0002] Satellite reception task planning is aimed at the satellite data reception tasks issued by various satellite agencies. Under the condition of limited ground reception resources, the satellite data reception tasks are comprehensively used to resolve the conflicts of ground reception resources by using the divide and conquer method and genetic algorithm to form a conflict-free and optimized solution. Satellite data receiving task planning scheme, in order to achieve the purpose of making full use of ground receiving resources. [0003] The traditional task allocation of satellite data reception relies on operators to manually allocate ground reception resources. This method has two defects. First, the utilization rate of ground receiving resources is low, especially under the premise of la...
