1995-043A
The third JCSAT satellite was an HS-601 model rather than the older spinning satellites used for JCSAT 1 and 2. It was launched on an Atlas 2AS, flight 8205/AC-117, on 1995 Aug 29. JCSAT 3 is owned by Japan Satellite Systems (JSS).
It is the first Japanese digital TV broadcasting satellite, and will be operated by DMC (Digital Multi-Channel Planning Co, Ltd), a partnership of JSAT (Japan Satellite Corp), Itochu Corp, Mitsui and Co, Ltd, Nissho Iwai Corp and Sumitomo Corp. The satellite will also provide data and fax transmission services.
JCSAT 3 was launched into a supersynchronous transfer orbit with an apogee of 80000 km. Space Command's circa-250-km initial perigee is a tracking error; the initial perigee was 167 km, a difference of 5m/s at apogee.
