GPS静态精密单点定位精度分析

Analysis on positioning precision of GPS precise point positioning

通过北京的IGS观测站数据,分析了精密单点定位的精度,结果表明,采用IGS提供的最终精密星历和钟差,经过40分钟的观测,可达到平面厘米级,高程方向最大误差在10厘米左右的精度.

This paper analyzes the precision of static GPS precise point positioning through the data of observation station in Beijing.The result shows that the accuracy can reach the plane centimeter level and the maximum error in height direction is about ten centimeter by using the final precise ephemeris and clock correction provided by IGS after forty minutes of observation.
