SHARP system for personal communications

Abstract

The application of the stationary high altitude relay platform (SHARP) concept orignally developed by the Department of Communications to provide a wide range of personal communications services is addressed. The inherent merits of SHARP are ideally suited to personal communications particularly to overcome some of the limitations of the geostationary satellites (GEOS) and low earth orbit satellite systems (LEOS) when used in personal communications environment. An overview of the SHARP concept is presented, and some of its merits are outlined. High level networking concepts are presented for typical cases as applicable to personal communications.
