Experimental and pre-operational issues for the next generation of business communications satellites
Abstract
The analysis of the operational constraints and forecast traffic requirements for the next generation of business communications satellites demonstrates that the 14/12 GHz will not provide adequate capacity for such a purpose. The use of higher frequency bands at 30/20 GHz will therefore be necessary and will raise a number of problems, in relation with the connectivity loss induced by the use of highly directive satellite antennas, and with the emergence of new concepts and technologies. Before such frequency bands are operationally introduced, it is therefore necessary to make sure that the techniques considered are mature enough to be implemented in this context. After a review of the general technical and operational background, the present paper discusses the experiments which are now being considered in the framework of the ATHOS experimental satellite project.
