| 摘 要： | 利用自动精密定位服务（APPS）、GPS分析定位服务（GAPS）、加拿大空间参考系统（CSRS）以及magicGNSS四个在线精密单点定位（PPP）网络数据处理软件，分别采用静态、静态模拟动态方式处理了若干国际GPS服务（IGS）跟踪站的观测数据，比较分析了四个在线PPP定位服务的数据处理能力及其精度。结果表明：不同的PPP在线定位服务的定位精度及其稳健性有所差异，但基本上都能够满足静态mm-cm级，动态1～2dm的定位精度。

| Abstract: | Several on-line PPP network data processing services such as APPS,GAPS,CSRS and magicGNSS,are introduced and analyzed in this paper.Both the static and kinematic modes are adopted for PPP solution using several observation data from IGS tracking stations with the four online services.The availability and accuracy of all these on-line PPP services are analyzed and compared.The results show that,although the positioning accuracy and stability of different service differs to some extent,the accuracy of static ... |
