Abstract
This paper represents the results of a comparison study of different troposphere models and different mapping functions and combinations between them for calculating the troposphere delay of GPS radio signals. The best accuracy of GPS receiver is used for estimation of the best combination between troposphere model and mapping function. Local meteorological data is used in calculations. The generated data can remove troposphere error and increase the accuracy of GPS measurements.
