Abstract

This paper addresses the Test User Receivers (TUR) of the Galileo Satellite Navigation System. The paper explains the concept of TURs highlighting the difference between TUR and a commercial receiver. An outline of the high-level requirements for the TUR is provided. Functional and performance requirements are presented. The interfaces between the TUR and the Galileo System are summarized, in particular the signals in space of the Galileo System. The key differences between Galileo and GPS receivers are identified, explained, and discussed.
