Abstract: An antenna system is provided for a satellite. This may include a main reflector (100), a subreflector (110), a boom including a first boom component (88) to support said main reflector and a second boom component (86) to support the subreflector. The first boom component may include a first main support (130), a fitting (150), and a second main support (140). The fitting may couple the first main support and the second main support. A positioning mechanism (120) may be provided within the fitting to support the main reflector. The positioning mechanism may be capable of adjusting a position of the main reflector.

Abstract: The projection of a planar distorted pattern onto a three dimensional surface provides a true or undistorted pattern on that surface. Complex patterns are applied to an irregular or curved surface by a method which includes the formation of a graphics display of the body on a computer graphics display and conversion to a two dimensional CADAM data base containing a planar projection of the pattern intended for application to the curved surface. This pattern information is translated into other forms, such as the form of a numerically controlled milling machine tape or photo mask, which is then used by ancillary method apparatus to form the desired pattern as a part of the method. The process describes the construction of a dichroic parabolic RF reflector.
