Abstract:	The Galileo Test User Segment (TUS) is being developed by the European Space Agency (ESA) to support the socalled In Orbit Validation (IOV) of the system. The Galileo TUS is composed of the Test User Receiver (TUR), the PRS-TUR, Test Support Tools (TST) and Search and Rescue (SAR) test beacon. The EAGUR consortium, lead by Septentrio, is in charge of one of the TUS developments. In this context, the work to be undertaken includes the consolidation of the test user requirements, providing high-level performance analysis of the TUR and PRS-TUR. This task, lead by QinetiQ, is mainly devoted to assess the ranging and the position, velocity, time (PVT) performance requirements of the TUR including the User Equivalent Range Error (UERE), and User Equivalent Range Rate Error (UERRE) budgets. In this paper, the atmospheric, thermal noise, interference and multipath contributions to the UERE budget results are presented. They include the pseudorange errors for all the Galileo carriers in different environmental conditions defined by ESA, such as aeronautical, rural pedestrian, rural vehicle and fixed user.
