ITU-R S.1758 PDF

This Recommendation characterizes high Earth orbit (HEO)-type fixed-satellite service (FSS) systems for the purpose of sharing studies. It intends to provide administrations with information on HEO-type FSS systems for use in sharing studies with other types of non-GSO FSS systems, with GSO FSS networks, and with systems and networks in other services allocated on a co-primary basis with the FSS. The information includes items such as orbit characteristics, active arc, repeating grounds tracks, antennas of associated earth stations, elevation angles, handovers and angular discrimination from the GSO arc.
