GALILEO Test User Segment – Phase C0 

Consolidation of the User Requirements for the Galileo Test User Segment 

Brief Description
Starting from the system requirements the Galileo Definition Phase has led to segment level requirements. For the Test User Segment (TUS) the requirements are defined in the User Segment Requirements (USREQ). The Galileo In Orbit Validation (IOV) TUS will receive and monitor the Signal in Space as broadcast by the experimental system test bed (GSTBV2) and IOV satellites.
Objectives of Phase C/D/E1: The overall objective of the Phase C/D/E1 activities related to the Test User Segment is the development of receivers to validate the Galileo performance for the different services identified in the Galileo System Requirements Document (GSRD) and to support additional demonstration and experimentation.
Objectives of Phase C0: The objective of Phase C0 was to freeze the user segment requirements and manage them under configuration control. Starting from there a preliminary receiver system architecture design was performed and detailed subsystem specifications have been derived. In addition the test support tools have been identified and specified. Phase C0 concluded with a successful Preliminary Design Review (PDR) for the different types of receivers. A successful PDR for the TUS required confirmation of compliance to high level performance allocations in range (UERE residuals) and position domain as well as for integrity. This had to be achieved through high level analysis and simulation.
