GPS Clock Algorithm in cdma2000-1x Systems

This paper introduces a method to capture accurately GPS clock under a simple and perfect automatism model.Then it is applied to the cdma2000-1x system.Mathematic derivations show that the GPS clock obtained with the proposed algorithm can reduce the clock precision loss resulting from instability factors of the hardware of GPS clock.And it can adjust periodically GPS clock and control the clock precision in to the range of 100ns.The algorithm is very simple.Calculation results demonstrate that the proposed algorithm can improve clock precision greatly.
