Abstract
The invention relates to a satellite telecommunications system featuring multi-beam coverage and dynamically controlled allocation of the satellite transmission capacity, of the type where a number of earth stations are linked to a satellite on board which regeneration of the earth-to-satellite signal is brought about. The system also features a modular beam-switching pattern and utilizes asynchronous protocol procedures for the exchanges between earth traffic stations and master station relative to telephone conversations and videoconferences, and for remote control of an on-board switching matrix (2) which operates the system, that is, allocates the satellite's transmission capacity so as to serve all the earth stations.
