Test and analysis for precision of GPS precise point positioning
Xiaohui Wang · Journal of Chinese Inertial Technology · 2006
PPP(precise point positioning) is one of the hotspots in GPS research field.The paper introduced its math model and data-processing scheme,described the effects of different IGS products on the solution results and presented the testing process and the data analysis result for PPP in static and dynamic modes.It was verified that this method of PPP could reach the precision of centimeter-level(in WGS-84 coordinate),and the convergence time is generally within 30 min.
