Facilitating the Commercialisation of Galileo through Signal Design

Matt O' Donnell, Mark Stevens and John Gallimore

Abstract:	Studies conducted over the last 18 months as part of the Galileo definition and development phases have demonstrated that a viable system can be developed and operated under a Public-Private Partnership (PPP) between the European Union and industry, based primarily upon the provision of mass-market services to end users. Both the public provision and revenue-related aspects of the services act as driving functions on the technical implementation of the system, especially the specification of the Navigation Signal in Space (SIS). As a founding member of Gailileo Industries and a major participant in the various Galileo Definition Phase studies, Astrium has been ideally placed to optimise the technical aspects of the SIS in order to facilitate the PPP initiative. This paper reviews the current thinking on necessary service preconditions for a successful business case and for the maximisation of social and macro-economic benefits, and shows how they can be translated into drivers on service mapping and signal design. Signal concepts are described that will help to achieve compliance against the requirements, with some counterintuitive conclusions drawn regarding the technical solutions for the SIS.
