An ARIANE 5 ECA ( Cryogenic Evolution type A), the most powerful version in the ARIANE 5 range, will be used for this flight. Flight 199 is a commercial mission for Ariane 5. The L557 launcher is the first in the A5ECA family to be delivered by ASTRIUM ST to Arianespace as part of the PB production batch. The PB production contract was signed in March 2009 to guarantee continuity of the launch service after completion of the PA batch comprising 25 A5ECA launchers, the last of which was launched on 26 th November 2010. The PB production batch comprises 35 A5ECA launchers and covers the period from 2010 to 2015. L557 is consequently the thirtieth complete launcher to be delivered to Arianespace , integrated and checked out under ASTRIUM responsibility in the Launcher Integration Building (BIL). In a dual-payload configuration using the SYLDA 5 “A” system and a long pattern fairing (total height: 17 m), the launcher is the satellites HISPASAT 1E in the upper position and KOREASAT 6 in the lower position.

  • KOREASAT 6 Ku-Band Commercial Communications Satellite
    KOREASAT 6 Ku-band Commercial Communications Satellite GEO Communications FACTS AT A GLANCE Mission Description Coverage: Orbital ATK teamed with Thales Alenia Space of France to supply the KOREASAT 6 commercial Korea communications satellite for KT Corporation of the Republic of Korea. Orbital ATK provided its GEOStar-2™ satellite platform; carried out engineering, manufacturing, integration and final spacecraft testing at its satellite manufacturing facility located in Dulles, Virginia; and performed launch site operations in Kourou, French Guiana. Thales Alenia Space was prime contractor for the project and provided the communications payload. In addition, the team delivered a ground system to support on- orbit operations of the satellite. Orbital ATK provided six months of on-site support after the satellite was handed over to the customer. KOREASAT 6 carries 24 Ku-band channels to provide Fixed Satellite Services (FSS) and six channels for Direct Broadcast Services (DBS) to the people of Korea. The spacecraft generates 3.4 kilowatts of Mission: payload power and has a 15-year on-orbit mission life. KOREASAT 6 was launched in December 2010 Ku-band communications to provide to a final orbital slot at 116 degrees East Longitude. Direct Broadcast Services (DBS) and Fixed Satellite Services (FSS) The GEOStar™ Advantage Customer: Orbital ATK’s highly successful Geosynchronous Earth Orbit (GEO) communications satellites are based KT Corporation on the company’s GEOStar spacecraft platform, which is able to accommodate all types of commercial (Thales Alenia Space – Prime communications payloads and is compatible with all major commercial launchers. The company’s Contractor) GEOStar product line includes the GEOStar-2 design, which is optimized for smaller satellite missions that can support up to 5.0 kilowatts of payload power.

Based on orbital data in ESA’s DISCOS database and on orbital data provided by KIAM the situation near the geostationary ring is analysed. From 1434 objects for which orbital data are available (of which 2 are outdated, i.e. the last available state dates back to 180 or more days before the reference date), 471 are actively controlled, 747 are drifting above, below or through GEO, 190 are in a libration orbit and 15 are in a highly inclined orbit. For 11 objects the status could not be determined. Furthermore, there are 50 uncontrolled objects without orbital data (of which 44 have not been cata- logued). Thus the total number of known objects in the geostationary region is 1484. In issue 18 the previously used definition of ”near the geostationary ring” has been slightly adapted.

  • Fr-Hispasat 1E & Koreasat
    UN LANCEMENT POUR L’ESPAGNE ET LA CORÉE Pour son sixième lancement de l’année, Arianespace mettra en orbite deux satellites de télécommunications : Hispasat 1E pour l’opérateur espagnol Hispasat et KOREASAT 6 pour l’opérateur coréen Korea Telecom Corporation. Le choix d’Arianespace par de grands opérateurs et constructeurs du secteur des télécommunications spatiales illustre la reconnaissance internationale d’un service de lancement de qualité. Par sa fiabilité et sa disponibilité, Arianespace reste le système de lancement de référence mondiale. Aujourd’hui, Ariane 5 est le seul lanceur opérationnel disponible sur le marché commercial capable de lancer deux charges utiles simultanément. Hispasat 1E sera le sixième satellite espagnol lancé par Arianespace. Le lanceur européen a mis en orbite en 1992 et 1993 les satellites Hispasat 1A et 1B. En 2005 et 2006, Hispasat et sa filiale Hisdesat ont fait confiance à Arianespace pour les lancements des satellites XTAR-Eur et Spainsat. En octobre 2009, Arianespace a mis en orbite le satellite Amazonas-2 pour l’opérateur Hispasat. Hispasat-1E a été construit par Space Systems Loral à partir d’une plate-forme LS 1300 et aura une masse de 5 320 kg au décollage. Equipé de 53 répéteurs actifs en bande Ku et d’une capacité supplémentaire en bande Ka, ce puissant satellite fournira une capacité supplémentaire à l’opérateur Hispasat et une offre de service plus large, vidéo et données, avec une couverture européenne et pan-américaine. Hispasat 1E aura une durée de vie de 15 ans et sera positionné sur une orbite géostationnaire à 30° Ouest. KOREASAT 6 est le deuxième satellite qu’Arianespace lancera pour l’opérateur sud-coréen Korea Telecom, après KOREASAT 3 lancé en 1999.
