摘要
分析了天地基测控资源的特点和高中低轨道航天器测控需求，以任务可能开始时刻作为调度决策变量；考虑了航天器用户方和测控设备管理方的测控要求，以最大化测控任务满足率和测控设备利用率加权和为调度目标，建立了天地基测控资源调度模型；采用了基于拉格朗日松弛算法的调度策略。仿真结果表明，模型及算法对解决天地基测控资源调度问题是可行的。
The performance of TT＆C resources of tracking and data relay satellite system （TDRSS） and ground stations and the TT＆C requirement of high and middle and low orbit spacecraft are analyzed, and the possible begin time of task is adopted as decision variable of scheduling. The TT^C demand of spacecraft user and TT＆C equipment manager are considered, with the scheduling objective of maximizing the weight summation of TT＆C task satisfaction rate and TT＆C equipment utilization rate, the scheduling model of TT＆C resources of TDRSS and ground stations is established; and then the scheduling strategy based lagrangian relaxation algorithm is adopted. Simulation result demonstrates that the model and algorithm are feasible for solving TT＆C resources of TDRSS and ground stations scheduling problem.
