Effect of height variation on precise point positioning

Today, satellite systems dedicated geodetic mission yield high precise coordinate information. With the development of technology and related satellite systems, PPP (Precise Point Positioning) concept has emerged in positioning techniques. It provides a wide range of applications with high accuracy satellite orbit and clock information provided by some institutions and organizations. In this study, the performance of precise point positioning technique between online software and academic software was analysed. In addition, the stations were selected at different heights and the precision of the PPP technique at different heights was investigated. For this purpose, 20 IGS stations, which have 24 hourly data, were utilized. The data was then evaluated with the web-based online evaluation service, CSRS and the academic software BERNESE. BPE module of BERNESE software was used. The numerical results are compared and interpreted.
