载人航天测控通信系统

TT&C and communication system of Chinese manned space flight

在原有卫星测控网的基础上规划设计的载人航天测控通信系统与国际标准接轨,通过国内外的地面测控站和遍布三大洋的四艘远洋测量船保证了地面与飞船的测量控制和通信,实现了多项关键技术突破。它不仅能满足载人航天任务的高可靠、高精度、高覆盖、高速率的需要,还能同时为30颗以上卫星提供测控通信支持,这标志着我国自主发展的航天测控通信技术达到了世界先进水平。

Based on the satellite TT&C system,China has established an integrated S-band TT&C and communications system of manned space flight.This system is composed of the control centers,ground observation stations and the four vessels deployed in the three oceans to provide the wide coverage,high date rate and reliable TT&C and Communication services for Shenzhou-5 manned spaceship.It is also the only real-time communication link between the spacecraft and ground control.This network has acquired the capability of sharing TT&C resources with international networks,and it is capable of providing TT&C services for more than 20 near-earth orbit satellites and geo-stationary orbit satellites simultaneously.Advanced in all technical indices and with a complete range of functions,its technology is equal to the advanced international level.
