在数据中继卫星系统中,中低轨航天器常采用差模跟踪技术,完成对数据中继卫星的捕获跟踪,建立高速数据中继传输链路。文章根据某任务跟踪接收机实际设计参数,用Matlab/Simulink软件对和差通道相位差对跟踪性能的影响进行了仿真分析。
In the data relay satellite system, low-orbit orbit spacecraft often use differential-mode tracking technology to complete the capture of the data relay satellite tracking, the establishment of high-speed data relay transmission link. According to the task of tracking the actual design parameters of the receiver, the Matlab / Simulink software and the difference between the poor channel tracking performance of the simulation analysis.
