Perspectives on European satellite communications

The Intelsat System is the classic intercontinental transmission system for television signals and large FDM beams is outlined. An important medium for the transmission of small beams and of individual telephone communication traffic. With its satellites of continuously increasing size and complexity the fifth generation is now in operation, the sixth in development it provides the following capacities in several areas of its radiation: the 6/4-GHz range (C band) and the 14/11-GHz range (Ku band). The prevailing transmission technology in the Intelsat System was analog, however changeover to digital transmission technology with pulse code modulation (PCM) as source coding and using time division multiple access (TDMA), has commenced with the construction of the ground stations.
