Анотация: Satellite based positioning systems are widely used for various applications. There are several error sources that causes the estimated position and time measurements from satellite based positioning systems’ receivers such as GPS and GNSS to be inaccurate. The one of the significant error sources is tropospheric delay. The troposphere is the lowest layer of the atmosphere near the earth that causes the largest error source of pseudo-lite signal as it propagates through the lower troposphere, and the thickness of it is 9-16 km. The GPS signal path through troposphere depends on temperature, pressure, height, latitude, and humidity (Gurtner, et al. 1989). It is necessarily to correct the signal delay caused by the troposphere. This paper reveals the importance of the tropospheric delay modeling for precise baseline parameter estimation by assessment of tropospheric delay models, and mapping function used to model the tropospheric delay in Mongolia at different elevation angles (0°, 5°, 10°, 15°, and 20°). The paper also discusses the advantages and limitations of these models. Trimble Geomatic Office (TGO) software is used to analyze the data in the current study.
