Abstract

The authors describe the ITALSAT satellite network, which will operate with an onboard base band switching matrix. They describe the main features of the system architecture, satellite terminal, and control center and the overall preoperational network performance. The satellite network interfaces the terrestrial network with three types of traffic: trunk, split and DAMA (demand-assigned multiaccess). The digital streams carry voice (64 kb/s), data, videoconferencing, and 70 Mb/s digital TV. The heart of the satellite terminal is the TDMA (time-division multiple access) subsystem. The high bit rate at the TDMA interface (147 Mb/s) and the high computational and throughput requirements are emphasized
