Abstract

As the application research basis of navigation system,the phase or frequency data of in-orbit satellite atomic clocks directly affect the precision and accuracy of navigation system.This paper analyzes the stability of four types of data of GPS satellite atomic clocks which is provided by the official website of IGS using Allan variance method and reaches some beneficial conclusions.
