Selected Signal Analysis Results for Galileo

Abstract:	This paper will discuss some of the design drivers for the signal concept and frequency plan for the European Galileo RNSS system. The provision of positioning and time services is based on two main considerations: (1) a most efficient use of the available frequency spectrum including the new bands that were allocated to RNSS at the WRC2000 in Istanbul and (2) the intended interoperability of Galileo with GPS to create the next generation of GNSS before the end of this decade. Reference is made to the frequency plan that has been developed in the Signal Task Force of the European Commission which will be presented in an accompanying paper [2]. To make positioning and time performance of Galileo attractive for all potential user groups wideband signal concepts are proposed for the provision of Open Service, Safety-of-Life Service, and a Public Regulated Service respectively. Accuracy, availability and robustness requires careful signal design particularly in the environment of mobile propagation channel. This paper will discuss various signal design concepts that have been investigated to support this objective. The signal design is driven by the anticipated receiver processing performance for future dual-system reception (GPS+Galileo) and by the sharing constraints of frequency spectrum to enable low-cost receivers particularly in the consumer electronic domain.
