针对航天器现有窄波束中继终端天线在姿态快速变化及姿态异常条件下提供测控支持的局限性,提出了利用宽波束中继技术提供测控通信支持的方案。基于宽波束中继天线性能、天地链路性能对测控通信支持的影响分析,提出了改善链路性能的优化方案。结合空间站任务载人航天器各阶段测控通信支持的特点,分析了宽波束中继在入轨段、长期运行段和返回段的应用。分析结果表明:宽波束中继可为载人航天器从海南发射场发射时的入轨提供测控支持,也可为载人飞船返回提供测控支持。
Aiming at the limitations of spacecraft existing narrow beam relay terminal antenna to provide the measurement and control support under the condition of rapid changes in attitude and attitude anomalies, a scheme of using wide beam relay technology to provide the measurement and control communication support is proposed. Based on the analysis of the performance of wide-beam relay antenna and the performance of world-wide link to the measurement and control communication support, an optimized scheme to improve the link performance is proposed. Combined with the characteristics of the measurement and control communication support of manned spacecraft in space station mission, the application of wide beam relay in orbit, long-term operation and return is analyzed. The analysis results show that the wide beam-to-beam relay can provide the measurement and control support for the manned spacecraft to launch into orbit from the launching site of Hainan and provide the monitoring and control support for the manned spacecraft’s return.
