摘要
针对载人空间站工程对测控通信系统提出的更高测控覆盖率、更高可靠性、长时间连续测控、高数据传输速率、多目标同时测控等需求,提出了采用天地基相融合的测控通信模式,构建以中继卫星系统为主的天基测控通信模式,利用"北斗"卫星导航系统实现自主可控的高精度轨道确定,合理布局和调度地面测控站,提升地面站工程遥测码速率和双目标支持能力,实现减站增效。对天地基测控资源进行一体化考虑,实现按需调度,完成空间站持续高可靠测控通信任务。讨论了测控数传一体化发展思路,建设Ka频段测控站,同时实现测控和高速数据传输。基于IP(互联网协议)开展天地一体化设计,提出了网络化测控的思路。
A TT＆C （Tracking, Telemetry and Command） and communication mode combining space-based and ground based TT＆C systems is proposed to meet the requirements of high coverage, high reliability, long-time continuous tracking and control, high data rate transmission and multi-target TT＆C of China＇s manned space station program. Tracking and data relay satellites are used to facilitate space-based TT＆C and communication and Beidou satellite navigation system is used for autonomous and controllable high accuracy orbit determination. The layout and scheduling of ground TT＆C stations shall be optimized to increase telemetry data rate and enhance dual-target support capability and to achieve synergy among the limited number of stations. Space-based and ground-based TT＆C resources shall be integrated and on demand scheduling mode shall be established to meet the requirements of long-duration and high reliability TT＆C and communication. Discussions are given on development of integrated TT＆C and data transmission, using Ka-band TT＆C stations for simultaneous transmission of TT＆C and high rate data. Finally, an inter-networking TT＆C approach featuring design of an integrated IP （Internet Protocol）-based space and ground system is presented.
