摘要
GEO卫星转发器在通信、时间频率传递及导航领域均有应用,测量卫星转发器本振频率对GEO卫星应用系统了解卫星转发器信息、分析系统信号性能、实现标准时间和频率传递等方面有着重大的意义。论文提出一种利用卫星转发导航系统地面站单频信号测距信息对卫星转发器本振频率进行测量的方法,利用导航信号综合基带自发自收单频信号,根据地面站综合基带测量得到的信号频率计算卫星转发器本振频率。该方法可实现实时在线测量在轨运行的卫星本振频率。实际测量结果表明,该方法的相对测量准确度优于2.3e-10。
GEO satellite transponders have applications in the fields of communication,time frequency transmission and navigation. Measuring satellite transponder LO frequency is great significance for GEO satellite application systems to understand satellite transponder information and analyze system signal performance and transmitting time or frequency information. This paper proposes a method for measuring the local oscillator frequency of a satellite transponder by using single-frequency signal ranging information from a ground station. We use navigation equipment to launch single-frequency signals and receive the signals at the same time,and calculate the transponder's local oscillation frequency in real time. and can calculate the transponder's local oscillation frequency in real time. This method can realize on-line measurement of on-orbit satellite local oscillator frequency in real time. The actual measurement results show that the measurement accuracy of this method is better than 3e-10.
