风云二号三点测距系统是风云二号静止气象卫星应用系统指令与数据接收站的重要组成部分,其主要完成对风云二号卫星的轨道位置精度定位任务。其测距精度与测距方法和标校零值等多种因素有关。静止气象卫星测距系统采用的是伪码测距方法,零值测定、装订以及是系统中测量精度误差的主要来源,本文主要分析了其标校零值的测定以及距离计算过程,且对任务中相关零值的装订方法进行了说明。
The FY-3 three-point ranging system is an important part of the FY-II stationary weather satellite application system command and data receiving station, and mainly accomplishes the task of locating the orbital position accuracy of the FY-2 satellite. Its ranging accuracy and distance measurement methods and standard calibration value and other factors. The static meteorological satellite ranging system uses the pseudo-code ranging method, zero value determination, binding and the main source of measurement accuracy error in the system. This paper mainly analyzes the determination of the standard calibration zero value and distance calculation process, The related zero value binding method is described.
