 1999-006A

---

JCSAT 4A (also called JCSAT 6) is an HS-601, delivered May 1998, 32 Ku tsp. to be launched by Atlas 2AS in 1999 into supersynch transfer orbit. Launch mass is 2900 kg, dry mass is 1226 kg.

The satellite will replace JCSAT-4 which will become a spare; that replaced JCSAT-1 in 1997. Launch of JCSAT-6 by Atlas 2AS was delayed following the SCP problems with several on-orbit HS-601s. JCSAT 6 will operate at 124E.
