ABSTRACT

The processing of Global Positioning System (GPS) observations for high-precision network establishment requires models to reduce the influence of systematic errors. One of the crucial sources of these errors is tropospheric refraction, particularly its changes and influence on height determination in local precise GPS networks, especially those located in mountainous areas. The authors’ present results of GPS data processing of local precise geodynamic research network ŚNIEŻNIK2001 (Sudetes, SW Poland) using different input data (standard atmosphere, ground meteorological data) and different methods of tropospheric delay estimation. Bernese GPS Software v. 4.2 was used, as an analytical tool.

Key words: GPS, tropospheric delay estimation, satellite leveling.
