Technical means for expanding the fixed-satellite service
Abstract
In connection with the rapidly growing use of the geostationary satellite orbit (GSO) for the fixed-satellite service (FSS), there is widespread concern that the medium may become congested. In order to ensure that each country's access to the radio spectrum from the GSO is adequate in capacity, there is a need for progress in two broad areas of concern to the International Telecommunication Union (ITU). A general improvement is required in some of the characteristics of FSS satellite networks, and there must be improvements in the technical means which are employed for managing the use of the GSO by the FSS. A number of aspects regarding these two areas are discussed in a report from a meeting of the Interim Working Party 4/1 (IWP 4/1). The present article provides a brief review of four of these aspects. Attention is given to satellite antenna radiation patterns, earth station antenna side-lobe response, frequency coordination of FSS networks, and flexibility in the positioning of satellites.
