JCSAT-4A, designated JCSAT-6 before launch, is a Japanese geostationary communications satellite which is operated by JSAT Corporation (now SKY Perfect JSAT Group). It is positioned in geostationary orbit at a longitude of 124° East, from where it is used to provide broadcasting and corporate network communications to Japan.[1]
Spacecraft description[edit]
JCSAT-6 was constructed by Hughes, based on the HS-601 satellite bus. It is equipped with 32 Ku-band transponders, and at launch it had a mass of 2,900 kg (6,400 lb), with an expected operational lifespan of fourteen and a half years.[2][3]
Launch[edit]
It was launched atop an Atlas IIAS launch vehicle flying from Launch Complex 36A at the Cape Canaveral Air Force Station. The launch occurred at 01:45:26 UTC on 16 February 1999,[4] and successfully placed JCSAT-6 into a geostationary transfer orbit. From this orbit, the satellite raised itself into a geostationary orbit using an R-4D apogee motor.[5] The final burn to complete its insertion into geosynchronous orbit occurred on 1 March 1999.[6]
