Zusammenfassung:	A method and apparatus for producing contiguous spot beam communications coverage on the Earth's surface are disclosed. The apparatus comprises an antenna system including two wide scan antennas (402, 404) and two narrow scan antennas (406, 408). The two wide scan antennas (402, 404) are disposed substantially opposite each other, and the two narrow scan antennas (406, 408) are disposed substantially opposite each other and substantially normal to the wide scan antennas (402, 404). The first wide scan antenna (402), second wide scan antenna (404), and first narrow scan antenna (406) produce a first beam pattern (414) on a planetary surface and the first wide scan antenna (402), second wide scan antenna (404), and second narrow scan antenna (408) produce a second beam pattern (416) on the planetary surface (Fig. 4A).
