JCSAT-4A, previously designated JCSAT-6, 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]

JCSAT-6 was constructed by Hughes, based on the HS-601 satellite bus. It is equipped with 32 J band (IEEE Ku band) transponders, and at launch it had a mass of 2,900 kilograms (6,400 lb), with an expected operational lifespan of fourteen and a half years[2][3]

It was launched atop an Atlas IIAS carrier rocket flying from Space Launch Complex 36A at the Cape Canaveral Air Force Station. The launch occurred at 01:45:26 GMT 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]
