5 AT THE FOREFRONT OF INNOVATION KA-SAT, EUROPE S FIRST HIGH THROUGHPUT SATELLITE DESIGNED FOR BROADBAND EUROPE S FIRST DEMO ULTRA HD CHANNEL HEVC ENCODED, 50 FPS, 10-BIT COLOUR DEPTH EUTELSAT 172B, FIRST ALL-ELECTRIC EUROPEAN COMMERCIAL SATELLITE FIRST HTS MOBILITY PAYLOAD LAUNCH ON HOT BIRD OF EUROPE S FIRST HD CHANNEL IN MPEG-2 DVB-S 2010 SMART LNB PIONEERING CONNECTED TV SERVICES BY SATELLITE EUTELSAT 115 WEST B, FIRST ALL-ELECTRIC COMMERCIAL SATELLITE EUTELSAT QUANTUM, SOFTWARE-DEFINED SATELLITE REVOLUTIONISING TELECOM MARKETS EPIC Workshop October 24-25, Madrid 5

6 EP FOR ON-STATION USE: EUTELSAT 16C AND KA-SAT EUTELSAT 16C (SESAT-1) SESAT-1 (Siberian European SATellite) was manufactured by Russian ISS-Reshetnev (former NPO-PM) and derived from Express family. Payload manufactured by TAS (former Alcatel) Launched in April 2000 on Proton K-BlockDM direct to GEO Electric Propulsion System used for orbital acquisition, NSSK, EWSK and relocation. Designed for a nominal lifetime of 10 years, after 17 years EUTELSAT 16 C is still working properly as expected To be deorbited next January 2018 Ka-Sat KA-SAT was manufactured by Airbus D&S based on Eurostar 3000 platform Launched in December 2010 on Proton Breeze M and released in GTO Electric Propulsion System used for NSSK, orbit inclination and eccentricity control Designed for a nominal lifetime of 15 years, after 7 years Ka-Sat is performing fully according to specifications EPIC Workshop October 24-25, Madrid 6

7 A NEW DAWN FOR EP IN COMMERCIAL APPLICATIONS What makes Electric Propulsion proposition attractive for Electric Orbit Raising (EOR)? P (KW) 1 In the last decades, the installed power on Telecom GEO platform has been continuously growing. LAUNCH COST ( /KG) EP ATTRACTIVE FOR EOR! 2 New launch service providers have renewed competition in the launcher market driving down the launch costs 3 Necessary conditions created for EP to become an attractive value proposition also for EOR TIME EP Value for EOR: Further Reduction of the Cost per Transponder On Orbit! As consequence, new design of telecom platforms, with Electric Propulsion with primary functions are now proposed by all major spacecraft manufacturers EPIC Workshop October 24-25, Madrid 7

8 EUTELSAT TRACK RECORD IN ELECTRIC PROPULSION SESAT/EUTELSAT 16C (2000) ISS-RESHETNEV KA-SAT (2010) AIRBUS DS EUTELSAT 115 WEST B (2015) BOEING EUTELSAT 117 WEST B (2016) BOEING EUTELSAT 172B (2017) AIRBUS DS AFRICAN BROADBAND SATELLITE (2019) THALES ALENIA SPACE EUTELSAT 7C (H2 2018) SPACE SYSTEMS LORAL Electric propulsion for station-keeping, direct geo insertion Reduced cost per bit Electric propulsion for station-keeping to maximize the throughput Reduced cost per bit First full EOR for a commercial satellite Launched as a pair on Falcon 9, very competitive launch cost Second eutelsat full EOR Launched as a pair on Falcon 9, very competitive launch cost First European full EOR commercial satellite Compatible with Ariane 5 low position, reducing launch cost by ~40% vs. Upper position First full eor Spacebus Neo spacecraft Higher throughput and compatible with most competitive launch solutions First full eor Space Systems Loral spacecraft Compatible with Ariane 5 low position, reducing launch cost by ~40% vs. Upper position 8

9 EUTELSAT 172B HAS RECENTLY REACHED THE GEO ARC! Manufactured by Airbus D&S, derived from E3000 L platform High-capacity satellite to provide continuity and expansion in Asia Pacific region with 36 Ku band, 14 C band and 11 HTS Ku-band spotbeams Launched on 1 st June 2017 on Ariane 5 low position and separated in a GTO orbit (launch mass = 3550 kg) To be positioned at 172 East for a design lifetime of 15+ years EOR cruise phase started on June 8 th and was successfully completed on October 11 th after about 4 months So far the fastest full EOR for a GEO Telecom platform EPIC Workshop October 24-25, 2017 Madrid 9

10 OTHER MAIN COMMERCIAL APPLICATIONS FOR ELECTRIC PROPULSION In-Space Servicing Refuelling for lifetime extension Reorbiting or spacecraft rescue Orbital slot/orbit change In-orbit assembly/repair LEO Constellations Increase of lifetime Reduction of wet mass Challenge on EP cost reduction EPIC Workshop October 24-25, 2017 Madrid 10
