| 摘 要： | 中继卫星在地球同步静止轨道上运行,既能直视中、低轨道用户航天器,又能直视地面站,是沟通用户航天器与地面站的桥梁。中继卫星调度问题是一类非常重要的调度问题。基于约束满足理论,通过分析中继卫星调度问题的特点与约束条件,建立了中继卫星调度问题的CSP模型。利用卫星工具箱STK进行模拟仿真,对CSP模型进行了求解。结果表明,所建立的CSP模型是合理的。

| Abstract: | The relay satellite, circulating on the GEO (Geographic Earth Orbit), can view the user spacecraft on the LEO (Low Earth Orbit) and the MEO (Middle Earth Orbit) directly as well, and view the ground station directly. The relay satellite can be seen as the bridge between the user spacecrafts and the ground station. The scheduling problem within TDRSS (Tracking and Data Relay Satellite System) is a very important problem. It analyses the characteristics and the constraints of the relay satellite scheduling, and then builds the CSP (Constraints Satisfaction Problem) model of the problem based on CSP theory. The CSP model is solved with STK (Satellite Tool Kits) and simulation method. Computational experiments indicate that the performance of the CSP model is quite good. |
