摘要
中继卫星系统高覆盖、数据传输能力强,是航天测控网的重要组成部分。随着我国中继卫星系统的建设和不断完善,其对优化我国航天测控网结构、提升中低轨道航天器测控能力的作用日益明显。本文结合中继卫星系统的特点,分析了我国航天测控任务对中继卫星系统的应用需求,提出了在运载火箭测控、航天器入轨段测控、载人航天测控、卫星在轨长期管理等方面开展中继卫星系统应用的思路,梳理了运载火箭测控、航天器入轨及早期轨道段测控、飞船返回段测控、多址链路测控等方面需要解决的关键技术。
Tracking and Data Relay Satellite Systems（TDRSS）,which feature high coverage and data transmission capability,have become a key part of space TTC（Tracking,Telemetry and Command） networks.The role of TDRSS is more and more significant in improvement of China＇s space TTC networks and enhancement of their TTC capability for LEO（Low Earth Orbit） and MEO（Medium Earth Orbit） spacecraft with establishment and development of China＇s own TDRSS.The application demands of China＇s space TTC missions for TDRSS are analyzed based on the characteristics of TDRSS.An approach is proposed for application of TDRSS in TTC for launch vehicles,spacecraft orbit injection,manned spaceflights and routine management of in-orbit spacecraft.A summary of key technologies is given for TTC for launch vehicles,spacecraft orbit injection and LEOP（Launch and Early Orbit Phase）,spaceship return phase and multi-access links.
