GPS精密单点定位技术及其应用

Technique of Precise Point Positioning of GPS and its Application

介绍了精密单点定位的基本原理,利用IGS数据和产品验证了对流层天顶延迟和电离层总电子含量的解算正确性,给出了青岛地区对流层折射率和电离层电子密度剖面的探测结果。实验结果表明:精密单点定位技术应用于空间环境探测是可行的。

The principle of Precise Point Positioning （PPP） is introduced, and the estimating of tropospheric zenith path delay and ionospheric total electron content is valided using IGS data and product. Finally, the tropospheric refractivity and ionospheric electron density sounding results in Qingdao are presented. Experiments show that application of precise point positioning in spatial environment sounding is feasible.
