Direction Finding of Automatic Tracking in Relay Terminal of Launch Vehicle

箭载中继用户终端对中继卫星的捕获跟踪是建立箭星间数据链路首要前提。针对Ka波段波束窄、箭载设备小型化要求高等特点,提出一种利用火箭飞行、姿态等辅助信息的自动角跟踪技术,并利用仿真,验证该技术可实现高精度测向,可作为箭载中继用户终端自跟踪系统设计和工程研制的参考。

Capture and tracking for TDRSS of relay terminal of launch vehicle is the primary precondition of es- tablishing the data links between relay satellites and launch vehicle. In view of the narrow beam in Ka-band and the strict requirement of the pint-sized equipment by launch vehicle, the automatic angle tracking with assistant informa- tion of launch vehicle is put forward. The simulation results show that high performance of precision of direction find- ing can be achieved with this technology. It provides references to system design and engineering of automatic track- ing in relay terminal of launch vehicle.
