|Abstract:||The Global Navigation Satellites Systems (GNSS) are used every day in a huge panel of applications. Currently, the European’s GNSS has about 1 billion of estimated number of Galileo-enabled smartphones. Users expect from GNSS a reliable, robust, continuous and accurate service. CNES, the French Space Agency, is involved in independent Galileo performance assessment activities since the first GIOVE and Galileo Launches. CNES also performs a continuous monitoring of GPS and SBAS systems for years. Based on that experience, navigation performances are analyzed and compared in this paper, with figures and midterm trends for Galileo and GPS systems. While Galileo is on-track toward the Full Operational Capability (FOC), this paper synthetize the navigation performances achieved since the Initial Services Declaration and provide an instructive comparison with GPS, the first GNSS system to have ever been operational. The usual system driven performance metrics are computed both for GPS LNAV (L1 C/A) and Galileo (Open Services) for the longest period of time since the Galileo initial Services declaration in December 2016. This paper demonstrates that both Galileo and GPS performances are good with respect to the Minimum Performance Levels (MPL) defined in GPS SPS PS and in the Galileo OS SDD documents.|
