3 THALES NAVIGATION Présentation Galileo Overview 2 Galileo Overview Galileo Programme Galileo is an autonomous navigation and positioning services under civilian control compatible/interoperable with GPS. A Technical, Economic and Political Challenge. Galileo infrastructure implemented in three phases:  Development and In-Orbit Validation ( ) [under ESA control and budget]  Deployment ( )  Commercial Operations (from 2008) To complete the development phase  a single management structure: The Galileo Joint Undertaking (founded by ESA and EC) for the Applications and the Local Element.

4 THALES NAVIGATION Présentation Galileo Overview 3 Open service (OS): basic level dedicated to consumer applications and general- interest navigation. Safety of Life (SoL): a highly stringent service for use where passenger safety is critical. Commercial Service (CS): a restricted-access service for commercial and professional applications that require superior performance to generate value- added services. Public Regulated Service (PRS): a restricted service for governmental applications with high continuity characteristics. Search and Rescue Service (SAR): a humanitarian service to accurately pinpoint the location of distress messages from anywhere across the globe. Galileo Services (1/2) (5 positioning services ) Galileo Overview

6 THALES NAVIGATION Présentation Galileo Overview 5 Components of Galileo Global component (Galileo Core System): > Space segment (30 satellites in MEO shared in 3 orbital planes). > Ground control and Mission Segment. Regional component: providing an Optional Regional Integrity service. Regions will have the possibility to determine their own integrity information and broadcast it via the satellites. Local component: additional local signals providing additional performance in terms of accuracy, availability, continuity and integrity. Galileo Overview

7 THALES NAVIGATION Présentation Galileo Overview 6 Galileo Overview Signal in Space (1/3) 10 Navigation signals emitted in RNSS bands:  3 signals in the frequency range MHz (E6)  4 signals in the frequency band MHz (E5a / E5b)  3 signals in the frequency range MHz (E2L1E1)

8 THALES NAVIGATION Présentation Galileo Overview 7 Galileo Overview Signal in Space (2/3) Services allocation within Galileo signals:  6 are designed for OS and SoL (signals 1,2,3,4 [E5a/E5b] and 9,10 [L1] )  2 are designed specifically for CS (signals 6,7 [E6] )  2 are designed specifically for PRS (signals 5 [E6] and 8 [L1] )
