| 摘 要： | 推导了精密单点定位PPP(Precise Point Positioning)的基本原理及其解算流程。为达到分米级甚至厘米级的PPP精度,给出了基于传统模型PPP技术,PPP数据必须处理的几个关键问题。最终,在Matlab程序设计语言软件平台下开发了APTags 1.0软件包,并通过机载GPS动态数据测试得出了如下结论:序列历元的事后动态定位精确度在B,L,H方向优于25 cm(RMS);85%定位结果的精度优于15 cm的动态定位结果。APTags软件包获取的动态精密单点定位结果与传统差分定位结果基本吻合。

| Abstract: | The principle of the precise point positioning and calculating steps were deduced,PPP data should process several pivotal problems based on the traditional model PPP technology to obtain decimeter or centimeter lever of the PPP precision.Finally,the APTags 1.0 was developed under the Matlab programmer software environment.Conclusion was made,which the precision was better than 25 cm(RMS) on the B,L,Hdirections and 85%precision of the location was better than 15cm,after calculation conduced with the dynamic ... |
