The initial Galileo satellite positioning services, starting from the 15 December 2016, became available with a formal announcement of the
European Commission. This was the first step toward the Galileo system Full Operational Capability (FOC) and allowed many researchers to test
the new system. The aim of this paper is to show some results of kinematic tests involving a GNSS multi-constellation receiver able to acquire the
Galileo Open Service (OS) signal.
The acquired data were compared with the outputs obtained by a Mobile Mapping System (MMS) implementing integrated high-performance
GPS/INS measurements. Using GrafNav software version 8.80 all the possible operative combinations were tested and analyzed. The results,
referred to the performed experimental test, show that the new European system is characterized by a better planimetric performance with
respect to the other systems whereas, from an altimetric point of view, the GPS and Glonass systems perform bette
