| 摘要: |
| 针对中国载人航天任务中遇到的中继卫星雨衰问题，对当前“天链”系列3颗中继卫星Ka频段数传信道的雨衰性能进行定量分析，讨论了中继雨衰对载人航天任务可能造成的影响。依据分析结果，考虑环境条件、客观因素限制和载人航天任务的特点，提出了应对中继雨衰的飞控实施方案和减少雨衰影响的方法，可为后续载人航天任务提供参考。 |

| Abstract: |
| In order to cope with the problem of rain attenuation of relay satellites in manned space flight mission,this paper analyzes the rain attenuation performances of the three relay satellites which are involved in Tianlian series and operate in Ka band.Then influences of rain attenuation of relay satellites on manned space flight mission are discussed.Considering the environmental conditions,the objective constraints and the characteristics of China manned space flight mission,this paper proposes an implementation plan of flight control to deal with the rain attenuation of relay satellites in hope of providing reference for future manned space flight missions. |
