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.

  • 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.

Prepared by ESA Space Debris Office Reference GEN-DB-LOG-00270-OPS-SD Issue/Revision 21.0 Date of Issue 19 July 2019 Status Issued ESA UNCLASSIFIED - Limited Distribution ! Page 2/234 Classification of Geosynchronous objects. Issue Date 19 July 2019 Ref GEN-DB-LOG-00270-OPS-SD ESA UNCLASSIFIED - Limited Distribution ! Abstract This is a status report on (near) geosynchronous objects as of 1 January 2019. 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 1578 objects for which orbital data are available (of which 14 are outdated, i.e. the last available state dates back to 180 or more days before the reference date), 529 are actively controlled, 831 are drifting above, below or through GEO, 195 are in a libration orbit and 21 are in a highly inclined orbit. For 2 object the status could not be determined. Furthermore, there are 60 uncontrolled objects without orbital data (of which 55 have not been catalogued). Thus the total number of known objects in the geostationary region is 1638. Finally, there are 130 rocket bodies crossing GEO.
