Abstract:	During the GalileoSat Definition Phase, a Galileo System Test Bed (GSTB) has been defined as an integral part of the Galileo Design Development and Validation Phase in order to mitigate programme risks. The GSTB is subdivided in two main development steps, Version 1 and Version 2. This paper mostly focus on the GSTB V1 whose main objective is to reduce Galileo programme risk on ground segment development by anticipated experimentation on critical algorithms. The GSTB V1 experimentation in the different areas is presented, namely Orbit Determination and Time Synchronization, Galileo System Time and its steering to UTC/TAI, User Equivalent Range Error budget characterisation, SISA checking and Integrity Flag computation. Later on the paper focuses on the GSTB V1 core infrastructure, its architecture and operations. The paper concludes with an overview of the GSTB V1 schedule and the role of GSTB activities in the overall design, development and verification of the Galileo system.
