|Abstract:||A candidate specification of the protocol for the Galileo Open Service navigation message authentication (hereinafter referred to as OSNMA) has been implemented as part of the AALECS project (Authentic and Accurate Location Experimentation with the Commercial Service). The protocol has been integrated into an end-to-end demonstrator in order to evaluate its performance. The purpose of this paper is to present the testing framework that has been adopted in the AALECS experimentation activities and to report the first end-to-end test results. This includes worldwide service volume analyses with realistic satellite visibility and availability of satellites connected to the Galileo Uplink Stations, in order to characterize the entire system performance by simulation of the Galileo Full Operational Capability (FOC). These results allow evaluating in advance the achievable performances of a future Galileo OSNMA user considering the full system capabilities. This paper also partly addresses the fundamental requirements to implement Galileo Open Service Navigation Messages Authentication in the current and next generation of GNSS receivers, based on the lessons learned in the AALECS project.|
