卫星双模授时设备的关键技术实现

Realization of Key Technology of Dual Mode Satellite Timing Equipment

通过分析全球定位系统授时的缺点和北斗卫星导航系统授时的可行性,提出了卫星双模授时结合多时钟源的授时设备的设计方法,对授时设备中涉及的完好性监测算法和守时算法进行了研究,并给出详细的分析过程。

Through the application of the disadvantages of GPS timing and the analysis of the feasibility of BD satellite navigation system, this paper proposes a design method of the dual-mode satellite timing. Research is done on the integrity-monitoring algorithm and the punctual algorithm that are related in the timing equipment. Detailed analysis about two algorithms is given.
