JCSAT-4A, designatedJCSAT-6 before launch, is a Japanese geostationarycommunications satellite which is operated byJSAT Corporation (nowSKY Perfect JSAT Group). It is positioned ingeostationary orbit at alongitude of 124° East, from where it is used to provide broadcasting and corporate network communications to Japan.[1]
JCSAT-6 was constructed by Hughes, based on theHS-601satellite bus. It is equipped with 32Ku-bandtransponders, 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]
It was launched atop anAtlas IIASlaunch vehicle flying fromLaunch Complex 36A at theCape Canaveral Air Force Station. The launch occurred at 01:45:26UTC on 16 February 1999,[4] and successfully placed JCSAT-6 into ageostationary transfer orbit. From this orbit, the satellite raised itself into a geostationary orbit using anR-4Dapogee motor.[5] The final burn to complete its insertion into geosynchronous orbit occurred on 1 March 1999.[6]
