The Analysis of Smooth Switching between Primary and Backup Atomic Clocks on Navigation Satellite
摘要
Abstract
The atomic clock is the core equipment of the navigation satellite,responsible for maintaining the frequency and time signal,the stability of the frequency and time signal is the basis for providing continuous and stable navigation signal and service.The atomic clock will be forced to perform switching between primary and backup,due to the frequency and phase difference,the navigation signal cannot continue to be used.The technology of smooth switching between primary and backup atomic clocks on the navigation satel-lite is used to solve the problem,which ensures the continuity of the navigation signal and the availability of the navigation message. Therefore,the relationship between the switching between primary and backup and the service performance is an urgent problem to solve.This paper introduces the technology theory of the switching,analyzes the timing and strategy of switching,analyzes and gives the performance index of the switching between primary and backup.关键词
