The primary mission of the Galileo Reference Centre (GRC) is to perform independent monitoring of the Galileo Open Service, to report publicly the service performance and to establish long term cooperation with the European Union Member States. This project (GSA/GRANT/04/2016/SG2) is a coordinated effort among four partners from three EU members states (Netherlands, Sweden and Finland). The consortium provides GRC access to a range of facilities and expertise at the member state level for Galileo service performance monitoring. The consortium contributes with Galileo observation data from their respective national sensor networks. Additionally, the consortium generates independent monitoring products in the ranging, timing and positioning domains on monthly basis. Furthermore, several Signal in Space (SiS) monitoring campaigns are to be carried out with a 25 m radio telescope. These campaigns allow to assess the quality of the signals from the individual Galileo satellites in the radio frequency domain. Lastly, the project will assess the compatibility and interoperability between Galileo and other GNSS whenever feasible. GRC collects and integrates this variety of independent data from multiple sources. Public performance reports on the Galileo Initial Open Service are released quarterly by the European GNSS Service Centre.
