摘要

转发器卫星定位系统采用普通商用地球静止轨道通信卫星组合导航卫星星座。首先获取导航信号的观测数据。通过对这些数据的处理,分析了影响授时精度的各种误差源,并计算了可能对用户接收机能力产生较大影响的导航卫星信号频率差。最后,对转发器卫星定位系统的授时和测速性能进行了评价。

Performance evaluation on time and frequency transfer of transponder satellite positioning system
Transponder satellite positioning system uses common business geostationary orbit communication satellites to combine the navigation satellite constellation. We first obtain the observation data of navigation signal. By disposing these data, we analyze different error sources which could impact the timing accuracy, then calculate the signal frequency windage from navigation satellites that has the possibility to greatly impact the capability of user receivers. What's more, the evaluations on timing and velocity measurement performances of transponder satellite positioning system are given.
