Özet:

 

The Global Navigation Satellite System (GNSS) is one of the most important inventions in the history of the survey. GPS in 1974 and GLONASS in 1976 were established and used for military purposes, and they were opened to civil use since 1980 and 1982 respectively and started to be used in daily life. The GNSS system has developed very rapidly in line with technological studies and these rapid developments have directed scientists to develop new methods that can meet the needs of users and get the most accurate results. One of the best studies to minimize the effect on GNSS signals in the atmosphere is the use of dual-frequency GNSS receivers. These receivers can eliminate errors on GNSS signals in the ionosphere layer. However, they cannot eliminate the errors occurring in the troposphere layer. To eliminate these errors, the tropospheric effect can be minimized by measuring the humidity, temperature and pressure values at each point of the survey and using these values in calculations. But since this process will take a lot of time and is very costly, tropospheric models have been made by scientists. By using these models in GNSS software, the effect of the troposphere layer on the signals can be minimized. In this study, four different survey campaigns were conducted to observe the effect of Troposphere models under different atmospheric conditions. Topcon Tools ver.7 and Leica Geo Office 7.0 software were used to evaluate these campaigns. The effects of troposphere models on these calculations have been observed. The atmospheric values measured at the time of the session and the atmospheric values are taken from the General Directorate of Meteorology were included in the calculations and the results were compared.
