A commercial communications satellite system for Japan
Abstract
JC SAT will provide commercial Ku-band communications service to the Japanese islands commencing in early 1988. The satellite is a Hughes HS-393 with 32 transponders and a 27 MHz bandwidth. The communications payload has 40 for 32 redundancy with nominal 20 watt traveling wave tubes. Eighteen of the transponders contain linearizer-TWT combinations. This system will provide highly reliable service for the complete range of applications from TV broadcast to digital data dissemination using relatively small receiving antennas.
