Earth Coverage ('Footprint') of a Satellite-Borne Antenna

Abstract

An exact solution is given to the problem of the intersection of an arbitrarily oriented cone and a sphere for the application of finding the Earth coverage - footprint - of a narrow beam satellite borne antenna. Two cases are considered: when the pointing angles from the satellite are known, and when the coordinates of the point on the Earth toward which the boresight is aimed are known. The situation of partial coverage is also treated in detail. Examples are included to illustrate the method.
