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。

A solution using wide beam data relay technology to provide TT&C (Tracking,Telemetry and Com-mand)and communication support is proposed to make up for the limitation of current spacecraft-borne narrow-beam antennas of DRSS (Data Relay Satellite System)in fast changes of attitude and anomalies of attitude.An opti-mization approach is presented to improve link performance based on the impact of the performance of wide beam data relay antennas and space-ground link on TT&C and communication.Applications of wide beam data relay tech-nology in the orbit injection phase,routine operation phase and return phase of space station missions are analyzed considering the characteristics of TT&C and communication support in different mission periods.The results show that the new technology could provide DRSS TT&C support for both orbit injection for launch of manned spacecraft from Hainan launch site and return of manned spaceships.
