Interoperability of Global Navigation Satellite Systems

The Galileo programme is Europe’s initiative for state-of-the-art Global Navigation Satellite Systems (GNSS), providing a highly accurate, guaranteed global positioning service under civilian control. To be successful, Galileo needs be inter-operable with the other two operating GNSS: the American Global Positioning System (GPS) and the Russian system, GLONASS. The JRC performs simulations and measurements in GNSS in the JRC's European Microwave Signature Laboratory (EMSL) laboratory.

The minimum requirement is coexistence with other GNSS systems without harmful interference. This requires mutual agreements on the GNSS signal design and independent tools and laboratory-based measurements to verify compatibility with different GNSS systems, as well as with terrestrial communications services such as 4G broadband.

The JRC performs simulations and measurements in GNSS and is developing a simulation tool to perform compatibility studies on Galileo and GLONASS, Compass and GPS. It will crosscheck the results with those obtained by other independently developed tools.
