Posicionamento GNSS: comparativo de resultados de processamentos obtidos com o uso das constelações GPS, GLONASS e GALILEO

With the advancement of technologies available for carrying out GNSS positioning, the number of users of GNSS receivers is growing considerably, with the availability of receivers equipped with technologies that optimize and improve the quality of positioning.
In this work, analyzes were carried out on the results obtained through the processing of raw data collected with a GNSS receiver, using specific geodetic processing software, dividing the analysis of the results into two stages: GPS, demonstrating the results obtained using only the GPS constellation and in the second moment, using the GPS constellation combined with the other constellations of the GNSS system separately, demonstrating the results of the processing using the GPS constellation and another available constellation, such as the GLONASS and Galileo system constellations.
The results of processing files collected with different tracking time periods were analyzed, making comparisons of results and proving the improvement in quality of the final result of a georeferenced positioning using a GNSS receiver with all available constellations.
