Using Multiple GNSS Constellations in Satellite Navigation

Are receivers using multiple GNSS constellations really much more precise in connection with positioning? It is one of the crucial question on which we would like to answer. This answer is based on testing GPS receivers GPSMAP 64s in various conditions. Our testing of accuracy was organized on the GNSS testing base which was built in areas with different conditions for measurement, such as uncovered terrain sparse mixed forest, dense mixed forest and urban area. Two receivers were being used during testing. The first one was set to receive signal from all at the moment visible GPS and GLONASS satellites. The second one was set to receive signal from all at the moment visible GPS satellites only. All results were being stored in NMEA format 0183. Result of our testing clearly showed that receivers equipped with technology for using multiple GNSS constellations are much more precise especially in areas with difficult conditions for measurement.
