Comparative analysis of tropospheric delay models in Precise Point Positioning in satellite navigation systems GLONASS / GPS
Due to massive usage of satellite navigation systems in the world precision requirements become more important. In the last year there is a big development of Precision Point Positioning (PPP) methods. Thropospheric delay is one of the biggest sources of errors in positioning solution. In article the quality of error prediction is analysed for tropospheric delay models in PPP. There are the following models analysed: Black, Goad-Gutman, Goad-Gutman with height, University of New Brunswick, Saastamoinen, GCAT, MOPS, Neill. The special interest for PPP is in GCAT, MOPS and Neill models as they do not require weather information.
