Broadcasting Satellite Service: Minimum Elliptical Beam Determination
Due to international regulations and agreements, the broadcasting satellite service will develop as a limited-area service. Thus, narrow-beam transmissions will be the rule in that service. There are, in addition, technical reasons making narrow beams preferable. On both regulatory and technical grounds, it is important that such beams be as small as possible. A method is presented for finding a minimum ellipse touching at least three points on the perimeter of a given region on earth. Minimization of spillover radiation into neighboring territories is also discussed as the choice of the aforementioned three perimetric points affects it.
