A possible European satellite system for business communications for the next decade
Abstract
The paper analyzes a possible configuration for a business communications satellite system dedicated to Europe for use in the late 1980's time frame. This configuration is based on a random multiple access mode in the up-link, satellite on-board regeneration and packet switching with eight down-link antenna spot beams and 41 up-link beams. The technical parameters and link calculations of the system are fully described and compared with a more conventional system based on Satellite Switched TDMA (SS-TDMA) and 12 up- and down-link antenna beams. Advantages and disadvantages of the two systems are discussed with particular attention to the earth stations configurations and costs.
