Second generation business satellite systems for Europe
Abstract
Attention is given to the characteristics of the market and its growth trends, and possible second-generation business satellite systems for use in Western Europe starting in about 1990 are described. It is noted that the total satellite traffic may be very large, reaching 530 Mbit/s by 1996, and could be several times greater should a strong video market develop. A single TDMA system is proposed that is designed to meet customer needs. Spectral saturation is obviated by employing multiple spot beams working in both the available European exclusive frequency bands: 12/14 and 20/30 GHz. On-board switching between all the transponders at a common intermediate frequency or at baseband guarantees full user interconnectivity irrespective of earth-station location or operating frequency. Dual-band working also permits extremely economic use of satellite capacity even in the event of an uneven or unpredictable geographical distribution of customers.
