5. September 12-13, 20025 No technological challenge! Example of GSM cells via satellite deployed in 3 months in Mauritania TimbedraTintane But an economical challenge! Example of GSM cells deployed in Germany during the Elbe 2002 flooding with EveryCom

6. September 12-13, 20026 Mesa / Satellite integration benefit Use Existing satellite INTELSAT, EUTELSAT, ARABSAT,... PMR Global solution Support data, voice & video Robustness Group calls Emergency calls Satellite solution Support full duplex video, voice and data Fast deployment Single hop (voice) Backup of dedicated networks Reach any area

7. September 12-13, 20027 International missions Benefits of satellite coverage –Turkey, Algeria, Greece … Possibility of several cells Access to the world wide public network WHEN Relief / Humanitarian forces deployed need contacts with their headquarter Example with Eutelsat W3

8. September 12-13, 20028 International Charter Space and Major Disasters What is the Charter? –An initiative meant to develop a coordinated global response of space resources in times of natural or technological disaster. Members –European Space Agency Centre national d'études spatiales Canadian Space Agency National Oceanic and Atmospheric Administration Indian Space Research Organisation What space resources are currently available through the Charter? –The remote sensing satellites RADARSAT-1, SPOT, ERS-2, IRS, POES and GOES. How to transmit on the field?

9. September 12-13, 20029 Broadcast of Meteo informations l 200 Meteo France l > 400 end users stations A key issue for crisis & disaster relief

10. September 12-13, 200210 Get relevant information on stressed conditions Have a GLOBAL view of the disaster –Satellite, Aircraft imagery –Information from the field (video, high resolution image) But it is not quite effective today –Delay to get images (at least 24h)

11. September 12-13, 200211 Integration in the operations management Group 1 Group 2 High speed link Complementarities of the satellite : Backup of existing networks Broadband communication (video) VL OFF HR image

12. September 12-13, 200212 Connection between terrestrial, radio and satellite networks Mobile centre Regional centre Experts TETRAPOL networks Main centre Terrestrial Satellite Radio

13. September 12-13, 200213 n Improvement of existing services to end users: Corporate communications services  Lan interconnection, Multicast data services,Telephony / video conference services (VoIP), Internet / intranet services Communication services to SOHOs, SMEs, Teleworkers, Home Users n New services to end users: Meshed VPN communication services Extension of the existing broadcast services to interactive services Services for institutional users Satellite technology: on board switching (WeB) Two types of services on one platform –Access to public and private networks (inc. Internet backbone) –Mesh network Access mission Mesh RCSTs Mesh mission Gateways Access RCSTs INTERNET DVB-S DVB-RCS DVB-S DVB-RCS DVB-S DVB-RCS

14. September 12-13, 200214 Geo Mobile Point to point communication services Types of Services: –Remote connection to other terrestrial networks. –Connection between two users within the satellite network Mobile Terminals Service Gateway for S-Band mission Nomadic Terminals S-Band Mission S-Band Link Feeder Link n Improvement of services (compared with systems already deployed (Inmarsat, Thuraya) Increased spectrum availability for MSS services through use of S-band spectrum Increased ability to serve traffic hot spots Higher data rates for similar size terminals or smaller size terminals (down to palmtop) n New functionalities to satellite operators / service providers Secures S-band spectrum for MSS services

15. September 12-13, 200215 Optical link (Silex follow on) Types of services: –Vice-versa: the provision of information from the ground to these aircrafts in real time –The relay of data (typ. High data rate video) from an aircraft to the ground through a geostationary payload (Intersatellite link + feeder link) n Operational introduction of new services Operational concept already validated in orbit: a data link between Spot 4 and Artemis can be established using a laser beam as signal carrier Real time data collection and transfer Very high bit rate applications (several hundred of Mbit/s) at quasi-error free quality RF Link Optical Link GEO

16. September 12-13, 200216 Satellite roadmap StatusExpected in orbit date opportunities WeB system 1999 01  02 beginning of the WeB-Artes 3 phase1 program, funding by ESA WeB phase 2 2006first broadband regenerative payload for commercial operator Geo Mobile 99  00 00  now 01  02 01  04 S-UMTS study with ESA Participation to ASMS-TF with ESA and EC Advance mobile satellite system study with ESA Inmarsat programme (F1/F2/F3) 2007commercial or ESA satellite Silex follow on 2001First optical links between Spot4 and Artemis 2003 2007 Artemis in GEO orbit ESA relay

17. September 12-13, 200217 Satellite benefits Fast deployment of networks –When non existing or damaged terrestrial infrastructure Availability and reliability of the satellite –Look at capacity to preempt satellite transponder A very broad coverage, with as low as 3 satellites to cover all Earth Open system –Support most of communication application (satellite delay) Broadband communication –Video, images, voice, teleconference, data Secure communications –Compatibility with encryption techniques

18. September 12-13, 200218 Way forward for integration of the space component in MESA project Terrestrial and satellite networks development should be coherent Today, main topics are: –Allocated frequency band and associated coordination constraints –Air interfaces, for compatibility with user terminals –Connectivity requirements –Resources management –Network architecture, centralised or not –Network protocols to be supported –Applications requirements (real time)  An integrated MESA standardisation process including the space segment will guarantee a full interoperability with other elements of the MESA infrastructure
