Influence Analysis of Satellite Clock Offset in Precise Point Positioning

We analyzed and comparised the results of precise point positioning(PPP) using 5 min and 30 s intervals precise satellite clock offset provided by IGS,analyzed the influence of different kinds of precise satellite clock offset to the PPP result,with emphasis on initialization convergence time and positioning accuracy.The experimental results show that the accuracy results of static and kinematic PPP using 30 s precise satellite clock offset were better than those using 5 min precise satellite clock offset interpolation into the 30 s satellite clock offset.
