The French Telecom 1 program and system
Abstract
The Telecom 1 system will offer three principal services, corresponding to different frequency bands and to many types of earth stations: (1) domestic telecommunications at 6/4 GHz; (2) metropolitan specialized services (intra-company system) at 14/12 GHz; and (3) military classified services (Syracuse system) at 8/7 GHz. The 6/4 GHz payload has a repeater configuration similar to that of the 14/12 GHz payload and offers simultaneous reception of four channels and channel separation by two demultiplexers in carbon fiber. The 14/12 GHz payload offers simultaneous reception of six 36-MHz bandwidth channels. It also features a preamplification parametric amplifier and frequency transposition from 14 to 12 GHz.
