Electric Propulsion for Station Keeping and Electric Orbit Raising on Eutelsat Platforms
Electric Propulsion for Station Keeping and Electric Orbit Raising on Eutelsat Platforms 2015-b/IEPC-97 Presented at Joint Conference of 30th International Symposium on Space Technology and Science 34th International Electric Propulsion Conference and 6th Nano-satellite Symposium, Hyogo-Kobe, Japan July 4 – 10, 2015 C. Casaregola1 Eutelsat, Paris, 75015, France Abstract: With a fleet of 34 geostationary satellites and more than 30 years of service from space, Eutelsat is today Europe’s most long-standing satellite operator and one of the world’s leading satellite operators. The first two platforms using Electric Propulsion procured are SESAT-1 (EUTELSAT 16C) and KA-SAT, for which Electric Propulsion is limited to on-station operations. The successful demonstration of sustained capability of Electric Propulsion for these two platforms in addition to the extensive flight heritage with no significant anomalies demonstrated in the last decades on both commercial and scientific platforms, prove the high level of maturity reached by Electric Propulsion systems. Based on that and due to new attractive launch options, one full-electric platform - EUTELSAT 115 West B – has been procured and launched in March 2015. The launch of EUTELSAT 115 West B is a key milestone for telecom platforms as it makes Eutelsat the first Operator to use Electric Propulsion for a complete electric orbit raising. Two additional platforms – EUTELSAT 117 West B and EUTELSAT 172 B - are under procurement and will perform complete electric orbit raising as well. An overview of Eutelsat platforms using Electric Propulsion for station keeping and electric orbit raising is given in the paper. -
Ariane-DP GB VA209 ASTRA 2F & GSAT-10.Indd
A DUAL LAUNCH FOR DIRECT BROADCAST AND COMMUNICATIONS SERVICES Arianespace will orbit two satellites on its fifth Ariane 5 launch of the year: ASTRA 2F, which mainly provides direct-to-home (DTH) broadcast services for the Luxembourg-based operator SES, and the GSAT-10 communications satellite for the Indian Space Research Organization, ISRO. The choice of Arianespace by the world’s leading space communications operators and manufacturers is clear international recognition of the company’s excellence in launch services. Based on its proven reliability and availability, Arianespace continues to confirm its position as the world’s benchmark launch system. Ariane 5 is the only commercial satellite launcher now on the market capable of simultaneously launching two payloads and handling a complete range of missions, from launches of commercial satellites into geostationary orbit, to dedicated launches into special orbits. Arianespace and SES have developed an exceptional relationship of mutual trust over more than 20 years. ASTRA 2F will be the 36th satellite from the SES group (Euronext Paris and Luxembourg Bourse: SESG) to use an Ariane launcher. SES operates the leading direct-to-home (DTH) TV broadcast system in Europe, based on its Astra satellites, serving more than 135 million households via DTH and cable networks. Built by Astrium using a Eurostar E3000 platform, ASTRA 2F will weigh 6,000 kg at launch. Fitted with active Ku- and Ka-band transponders, ASTRA 2F will be positioned at 28.2 degrees East. It will deliver new-generation DTH TV broadcast services to Europe, the Middle East and Africa, and offers a design life of about 15 years. -
Classification of Geosynchronous Objects Issue 12
EUROPEAN SPACE AGENCY EUROPEAN SPACE OPERATIONS CENTRE GROUND SYSTEMS ENGINEERING DEPARTMENT Space Debris Office CLASSIFICATION OF GEOSYNCHRONOUS OBJECTS ISSUE 12 by R. Choc and R. Jehn Produced with the DISCOS Database February 2010 ESOC Robert-Bosch-Str. 5, 64293 Darmstadt, Germany 3 Abstract This is a status report on geosynchronous objects as of the end of 2009. Based on orbital data in ESA’s DISCOS database and on orbital data provided by KIAM the situation near the geostationary ring (here defined as orbits with mean motion between 0.9 and 1.1 revolutions per day, eccentricity smaller than 0.2 and inclination below 30 deg) is analysed. From 1161 objects for which orbital data are available, 391 are controlled inside their longitude slots, 594 are drifting above, below or through GEO, 169 are in a libration orbit and 7 whose status could not be determined. Furthermore, there are 77 uncontrolled objects without orbital data (of which 66 have not been catalogued). Thus the total number of known objects in the geostationary region is 1238. During 2009 twenty-one spacecraft reached end-of-life. Eleven of them were reorbited following the IADC recommendations, one spacecraft was reorbited with a perigee of 225 km - it is not yet clear if it will enter the 200-km protected zone around GEO or not -, six spacecraft were reorbited too low and three spacecraft did not or could not make any reorbiting manouevre at all and are now librating inside the geostationary ring. If you detect any error or if you have any comment or question please contact R¨udiger Jehn European Space Operations Center Robert-Bosch-Str. -
Realizing Resilient Tactical Networks with Maximum Government Control on High-Throughput Satellites
WHITE PAPER Realizing Resilient Tactical Networks with Maximum Government Control on High-throughput Satellites 1 Wide-beam connectivity is an essential aspect of military satellite communications and High Throughput Satellite (HTS) technology is proving to be ideally suited for many Government applications. While most satellite operators offer closed HTS architectures that are vendor-locked with very little control offered to users, the Intelsat Epic Next Generation (Epic) HTS architecture is enterprise- grade, open architecture and vendor-agnostic. Intelsat Epic allows Government and military access to bandwidth-efficient, higher data throughputs on a global-scale via a wide variety of user-chosen waveforms, modems and antennas. Intelsat is proud to present the next generation of satellite communications that features higher data throughput rates and security while offering cost-efficiencies across the board. Introduction High Throughput Satellites (HTS) have been the center of solutions. Interoperability between the various military attention for the past five years. It is important to note that branches, allied, and coalition forces continues to be a most of these systems have been purpose-built solutions to challenge. Finally, most military and government users require service homogeneous sets of users via closed architectures. operational coverage in remote and austere regions such Systems such as ViaSat Exede, Inmarsat Global Express, Hughes as deserts, jungles, and oceans—well outside of population Jupiter, and Eutelsat KA-SAT require new investments in centers for which these closed architectures are optimized. proprietary modem technologies and service architectures. These closed systems offer star-only connectivity and keep With the disconnects between these closed HTS solutions and quality of service control with the service provider, not the end the challenges faced by the Government, it is no wonder that users. -

GB-ASTRA 3B-Comsatbw-21Mai V
A BOOST FOR SPACE COMMUNICATIONS SATELLITES For its first launch of the year, Arianespace will orbit two communications satellites: ASTRA 3B for the Luxembourg-based operator SES ASTRA, and COMSATBw-2 for Astrium as part of a contract with the German Ministry of Defense. The choice of Arianespace by leading space communications operators and manufacturers is clear international recognition of the company’s excellence in launch services. Because of its reliability and availability, the Arianespace launch system continues to set the global standard. Ariane 5 is the only commercial satellite launcher now on the market capable of simultaneously launching two payloads. Over the last two decades, Arianespace and SES have developed an exceptional relationship. ASTRA 3B will be the 33rd satellite from the SES group (Euronext Paris and Luxembourg Bourse: SESG) to have chosen the European launcher. SES ASTRA operates the leading direct-to-home TV broadcast system in Europe, serving more than 125 million households via DTH and cable networks. ASTRA 3B was built by Astrium using a Eurostar E 3000 platform, and will weigh approximately 5,500 kg at launch. Fitted with 60 active Ku-band transponders and four Ka-band transponders, ASTRA 3B will be positioned at 23.5 degrees East. It will deliver high-power broadcast services across all of Europe, and offers a design life of 15 years. Astrium chose Arianespace for the launch of two military communications satellites, COMSATBw-1 and COMSATBw-2, as part of a satellite communications system supplied to the German Ministry of Defense. The first satellite in this family, COMSATBw-1, was launched by Arianespace in October 2009. -
