高精度连续时频信号产生和控制系统的分析

Analysis on the System for Generating and Controling Highly Precise and Uninterrupted Time

本文具体分析了NTSC和LORAN-C的两套时频基准系统。结果表明,LORAN-C的时频基准系统能够保证信号的瞬间连续性。它可广泛应用于守时、授时及导航系统中。

Two standard time and frequency systems used in the National Time Service Center （NTSC） and Loran-C are analyzed fully in this paper.The result shows that the system in Loran- C can ensures the instantaneous continuity of the signal.The latter can be widely used in time keeping time service and navigation systems.
