基于北斗一号的近地卫星天基测控技术及应用

Technique and Application of Space-based TT&C for LEOs Based on Compass-1 System

  • 摘要: 研究了利用北斗一号短消息传输功能支持天基遥测遥控技术;利用其授时功能支持星地时差测量技术;利用其定位功能支持近地卫星测定轨技术,解决了高动态、无高程信息下的北斗一号用户机的定位问题。并对“遥感卫星九号”获取的北斗天基测控试验数据进行了分析。结果表明,天基遥测遥控试验正常;星地时差测量精度满足星务计算机工作要求;仅利用两颗北斗一号卫星对“遥感卫星九号”的四程距离和数据确定的“遥感卫星九号”轨道,与事后精轨比较,半长轴误差约1m。

     

    Abstract: This paper proposes a method of using Compass-1's short message transmission function to support space-based TT&C technology,using its time service function to support space-ground time difference measurement technology,and using its positioning function to support orbit determination technology for LEOs.Currently,YG-9,the first satellite carrying a Compass-1 user receiver,has validated the key technologies of space-based TT&C.The test on YG-9 has shown that the space-based TT&C functions well,the precision of space-ground time difference measurement can satisfy the requirements of onboard computer,and the orbit accuracy of YG-9 can achieve 1m in semi-major axes with only the four-way ranging data between YG-9 and Compass-1.Finally,this paper analyzes the application foreground of Compass-1 space-based TT&C technology.
