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.
In 2003 he was graduated from the Military Academy in Brno. His first job after graduation was at the Military Geographic and Hydrometeorologic Office in Dobruska. His first position was in Department of Surveying and Mapping. He spent in this Department 7 years. During this time he was responsible for geodetic support of the Czech Armed Forces. After this piece of experience he was reassigned to the GPS Information and Monitoring Center. This workplace has been responsible for implementation of GPS technology into the Czech Armed Forces. In 2011 he was deployed to Afghanistan, where he was working under command of NATO-ISAF operation and he was responsible for geographical support of the Czech Contingent in province Logar. During his career he attended some special training courses abroad, such as Vulnerabilities of GNSS at the University of Nottingham or NATO Geospatial Orientation Course at NATO school in Oberammergau. At the present time Major Jiri Hubicka is chief of GNSS Department at the Military Geographic and Hydrometeorologic Office in Dobruska.
