基于CNES产品的GPS实时精密单点定位性能分析

Performance analysis of GPS real-time precise point positioning based on SSR products from CNES

文中基于CNES数据分析中心的实时精密轨道、钟差产品,利用数个国内IGS站数据进行GPS精密单点定位解算,并且与伪距单点定位及基于IGS最终星历的精密单点定位结果进行了横向比较。结果表明:现阶段实时PPP解算可实现分米级的定位精度。

In this paper,the data of several domestic IGS stations was used to perform GPS precision single-point positioning solutions based on the real-time precision orbit and clock difference products of the CNES data analysis center,and the results were compared with the pseudo-range single-point positioning and precision single-point positioning results based on IGS final Ephemeris.The results showed that real-time PPP could realize positioning accuracy of decimeter level at the current stage.
