摘要
分别采用IGS提供的5 min和30 s采样间隔的精密卫星钟差进行静态和动态精密单点定位实验,分析比较了采用不同钟差处理的精密单点定位结果,以及不同种类钟差对初始化收敛时间、定位精度的影响。实验结果表明,采用30 s精密卫星钟差的静态、动态精密单点定位结果精度均优于采用5 min精密卫星钟差内插成30 s钟差的静态、动态精密单点定位结果。
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.
