ESA has 17 member States :
• Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Norway, the Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
• Canada takes part in some projects under a cooperation agreement.
An inter-governmental organisation with a mission to provide and promote - for exclusively peaceful purposes - the exploitation of:• Space science, research & technology• Space applications
What is ESA?

All Member States participate in Space Science mandatory programmes.
• Human space flight and exploration
In addition, members chose the level of participation in optional programmes:
• Microgravity research
• Earth observation
• Telecommunications
• Satellite navigation
• Launcher development

ESA is fully independant from commercial operators
ESA is responsible for research and development of space projects.
Operational systems are transferred to new or specially established organisations:
On completion of qualification, these projects are handed over to outside bodies for the production/exploitation phase.
• Launchers : Arianespace - launcher production phase• Telecommunications : Eutelsat & Inmarsat - international communications
services via ECS/MARECS• Meteorology : Eumetsat - Meteosat weather satellites• Satellite Navigation : Galileo, Joint, Undertaking (with the E.U.)
7115 launches of ARIANE 4 for 155 satellites in total (1988-2003)
Telecom Satellites launched: 139
Others: 16
(Earth Observation + Weather + Science)
Telecom: a commercial success

The DVB-RCS standardfor broadband access
9
DVB-RCS defines a Return Channel over Satellite for broadband systems based on DVB-S
Specification initially defined by satellite operators working under the auspices of ESA
Work taken over by DVB Project, which is responsible for standard maintenance
ETSI approves its publication as EN 301 790, according to their defined procedures
Definition started in Sept 1997Editions
•1st (v1.2.2)12/00•2nd (v1.3.1) 03/03: RSAT•3rd (v1.4.1) 09/05: DVB-S2
DVB-RCS background
10
Defined by group of interested companies:scrutinised, optimised, built by consensus
Based on commercial requirements
Broad range of services and applications supported
Future-proof (e.g. DVB-S2)
Based on successful DVB-S: availability of mass market low costsatellite TV receivers
Enables interoperability between products
DVB-RCS is an Open Standard
11
Several system integrators
Several terminal suppliers
Different choices of options and parameters
Several generations of system implementations: cost & feature optimised
Multiple implementations of DVB-RCS
Enables interoperability between products
12
• Networks accept user terminals from several suppliers• User terminal operates in different networks
Definition of interoperability
13
ESA strategy for DVB-RCS
14
ESA fostered the creation of the SatLabs Group to:1. Ensure interoperability between DVB-RCS terminals and
systems 2. Achieve low-cost implementations of DVB-RCS products
ESA is chairing the SatLabs Group and leads most working groups
Key developments for the implementation of interoperability verification
are carried out by ESA– Common Test Bed for interoperability testing
ESA also funds key technological developments needed to reduce cost
– Low cost Components– Low cost installation mechanisms
ESA strategy for DVB-RCS
15
SatLabs Group basics
• Association set up to bring the DVB-RCS standard to large-scale adoption– Foster availability of interoperable products– Ensure availability of solutions for interoperability testing
and certification
• Membership open to all organizations worldwide interested in the DVB-RCS standard
• Main emphasis on interoperability but addressing other aspects related to DVB-RCS implementation
• Creation: October 2001

Qualification/Certification Programme status
• 1st Certificate issued in August 2005
• Since then 4 other terminal vendors obtained a certificate
• Others under preparation to start Qualification testing

DVB-RCS :Evolution and Benchmarking
22
Bit-rate gain (same C/N and symbol-rate) of 25-35% depending on modes and applications
Large flexibility to potentially match any transponder characteristics
Spectrum efficiencies from 0.5 to 4.5 bit/s/Hz C/N range from –2.4 to +16 dB with 1 dB granularity
DVB-S2 improvements
0.7 – 1 dB from the Shannon limit probably means that: “In the course of our lifetime we will never have
to design another system for satellite broadcasting”
23
Support of Quality of Service Support of DiffServ mechanisms (ie. PHB over DVB-RCS)
Performance Enhancing Proxy Definition of a standard PEP
Harmonised Management and Control Planes Extend standard toward higher OSI layers
DVB-RCS evolution: current topics
Standardisation work is on-going: all topics discussed at SatLabs Plenary session on 10&11 May 2006
24
Pilot projects for broadband connectivity
25
• ESA is supporting provision of new applications with commercial potential through Pilot Projects: all activities involve a user community through a pre-operational phase of actual utilisation of the system
• Several Pilot Projects address Broadband Access Services, e.g.
Inspire Pacific Skies
Applications
26
INSPIRE is a validation pilot services on a large scale (6000 users) to provide Internet access in selected non-metropolitan areas
– Provide WiFi connections to consumers
– Establish an operational 24×7 service addressing all key operational aspects such as billing, QoS, integration with terrestrial networks, installation, commissioning, maintenance etc.
– Charge end users at price comparable to xDSL.
– Collect detailed roll-out and operational information on an unprecedented scale to provide a massive “test bed” for Digital Divide hypotheses.
INSPIRE: broadband via DVB-RCS + WiFi

• That satellite broadband can service the needs of Home Users and SMEs in Rural Areas, the driving engine behind rural development
• That broadband via satellite is viable at competitive pricing throughout Europe
• Prove the business case for system with lower capacity costs
INSPIRE: what does it prove?
• That satellite can deliver comparable performance to terrestrial services
• It will be used to provide evidence that larger scale European plans are feasible and can help solve EU policy issues
29
INSPIRE: status
• Phase 1: Design and Procurement: – suppliers’ selection complete mid 2006
• Phase 2: Initial deployment– DVB-RCS hub commissioning completed May 2006– Basic Service Launch June 2006 with 100 terminals installed– Integrated quality of service support and advanced
management functions available by October 2006
• Phase 3: Large scale deployment– Interoperability between RCS terminals (at least two sources)– 600 terminals/6000 users “dense deployment” in place Q1
2007– Pilot operation until end 2007– Evaluation end 2007
