| Abstract: | This paper analyzed the structure and theory of the time system of GPS .The interaction between GPST, UTC and TAI was introduced.The setime systems have different mechanisms even though they are associated.The the sis expounded the important role that GPS plays in the worldwide time comparing.The mathematical models of GPS CV and GPS phase technology was developed, then we computed their precision using observation.Result shows the frequency stability of GPS CV and GPS phase technology is good. |
