Navigation Related communication Services, the case of a GALILEO Service Option

Raniero Pasquali

Abstract:	One of the options for GALILEO service elements are the Navigation Related communication Services (NRS): a two-way packed date communication capability bundled with GALILEO navigation services. The proposal of the NRS option for GALILEO service definition, obliges the navigation community to think around a change in the system and service paradigms defined (with success) by GPS. But from the Mobile Service Providers and the Final Users point of view this GALILEO perspective is quite natural, convergent and complementary to the tendency of UMTS NAV/COM service convergence. In the next decade scenario a (low data rate but RT) communication service integrated a (highly performing) navigation service from space, could really be synergetic with the (low performance) navigation and the (high data rate, high performance) communication services expected to be supported by the next generation of mobile radio network. NRS option for GALILEO is presented in the future evolution of navigation/location market structure and of the mobile services value chain. The comparative and competitive analysis of GALILEO NRS versus present and incumbent technologies (GPS and mobile communication networks) is here reported. The expected market associated to this service elements is therefore characterised and quantified. GALILEO NRS service performances and system design are defined starting from the findings of of different (but convergent) market analysis. The capability to provide from a GNSS constellation a bundled service competitive with the future NAV/COM integrated solutions is based on a market driven system design. Service performance, terminal weight, dimension and cost, as well as satellite antenna design have been defined starting from the NRS market needs and the GALILEO mission and design constraints. In conclusion here is shown as a system based on a 60Kg/600W bent pipe communication payload on each GALILEO satellite, can become one of the future standard platform for Personal Emergency, Fleet Management and Info-mobility applications. It is shown how GALILEO NRS alone can generate commercial revenues (from the European market) to largely balance the whole GALILEO (NAV and COM) operative costs. Finally in this paper it is detailed as the GALILEO NRS, costing 0.004-0.006 Euro for 100 Byte packet, could sustain a business case for a purely private financing approach to this element of GALILEO NRS technical and business case was studied in "PPP Case Study" for the European Space Agency, in "Euronav", "Sidereus", "GEMINUS" and "GALA" for the European Commission and in "STENAV" for the Italian Ente Nazionale Assistenza al Volo as well as in a number of internally funded studies.
