分布式卫星系统数传调度研究
Research on Transmission Task Scheduling for Distributed Satellite Systems
摘要
Abstract
With the increase of in⁃orbit sensing satellite,the current relay satellite system is facing a major challenge in terms of data transmission performance.While the payload capability is restricted by satellite platform,the distributed satellite system is a practi⁃cal solution to tremendously improve the performance of relay satellite system. The transmission task scheduling problem of distributed satellite system is studied, a multi⁃satellites multi⁃tasks transmission task scheduling model is proposed based on PSO algorithm by jointly considering constraint conditions such as the visible time windows between distributed satellite systems and user satellites in MEO and LEO, the residual resources of satellite systems and the property of user transmission tasks. Considering the number of scheduling tasks in practice,the typical PSO algorithm is modified and the proposed algorithm is verified by computer simulations.关键词
