| Sumario: | A complete automatic user application to show Dilution of Precision (DOP) values for a group of satellites from one or more GNSS constellations visible to a receiver on Earth has been designed and implemented. This user app, which is possible because of the interoperability among GNSS systems, gives an evaluation of positioning improvement by calculating the DOP using all available GNSS constellations. The application testing was possible using the National Active Geodetic Network of Mexico, which provides several positioning services. One of those services is in the form of RINEX files every 15 seconds for the entire territory and therefore, the DOP is obtained for that specific period. International agreements on the interoperability of GNSS reached in the International Committee on GNSS have allowed improvements of positioning services. Thus, on the one hand, active geodetic networks around the globe can be used to use GNSS system interoperability and, on the other hand, signal interoperability will very soon provide practical real time positioning almost universally. Multi-agent drones and automatic guidance for aircraft landings are among the many modern uses for the high precision navigation services made possible by interoperability. Therefore, there is a need for methods and algorithms to evaluate the improvement in GNSS positioning when using interoperability. This thesis presents a software development whose purpose is to determine the improvement in positioning due to the interoperability among the GPS, GLONASS and GALILEO systems. The developed methodology works autonomously to strip all position information provided by each RINEX file and automatically obtains the DOP for all satellites of the three constellations that are in the field of view of the receiver for each reference point of the active network. |
