Galileo Test User Receiver Status, Key Results and Performance

After the successful development and demonstration of the first GALILEO Experimental Test Receiver (GETR), Septentrio was awarded a contract with ESA to develop a reference GALILEO Test User Receiver (TUR) for the verification of the GALILEO IOV constellation and as a demonstrator for multi-constellation applications. This project is now in its final stage and the first IOV receiver units are now available for experimentation and testing. The TUR-N is developed to cover a wide range of receiver configurations to demonstrate the future GALILEO only and GPS/GALILEO combined services: GALILEO single and dual frequency Open Services (OS) GALILEO single and dual frequency Safety-of-Life Services (SOL), including the full GALILEO Navigation Warning Algorithms. GALILEO Commercial Service (CS, including tracking and decoding of the encrypted E6BC signal) GPS/SBAS/GALILEO single and dual frequency multi-constellation positioning GALILEO single and dual frequency differential positioning. GALILEO triple frequency RTK In parallel a similar Test User Receiver is specifically developed to cover the Public Regulated Service (TUR-P). Without the PRS components and firmware installed, the TUR-N is completely unclassified. The TUR-P will be covered in other publications and is not covered under this paper. The Septentrio development described in this paper is one of two parallel ESA activities, the other being led by Thales Avionics (F) where also PRS and non- PRS receivers are under development, as described in other publications. This paper will further elaborate on the Septentrio TUR-N architecture, its main distinguishing features, and present some example performance results.
