In the present work, the delay suffered by the GPS signal during the transmission through the propagation channel is analyzed, which is affected by factors, characteristics and conditions of the atmospheric layers. The troposphere due to the wet and dry components produces the hydrostatic delay which represents approximately 90% of the total delay of the signal that depends directly on the atmospheric pressure and the tropospheric delay which is influenced by the water vapor and the temperature. To estimate the delay, we chose the sample of the data of the days with the highest and lowest humidity and accumulated precipitation based on the Saastamoinen model, comparing the results with the analyzed data extracted from the EREC station of the GNSS Continuous Monitoring Network. Ecuador (REGME) through the processing of data with the RTKlib tool to assess the impact on the accuracy of the final solution in the positioning of the receiver.
