Television satellite system
专利汇可以提供Television satellite system专利检索，专利查询，专利分析的服务。并且The present invention generally relates to a long life television system carried aboard a passively stabilized satellite for continuously providing linearized, high resolution coverage of the earth or other body about which the satellite orbits. More specifically, the proposed system of the present invention operates on a line-scan principle; i.e., the satellite carries a lens system whose field of view is a narrow, elongated swath on the earth''s surface which advances due to the satellite orbital motion. A fiber optic assembly receives the light image from the lens system and transfers it, as a substantially square raster, to the photosensitive faceplate of an image dissector camera tube, for example, where the image is then electronically scanned at a rate dependent upon the time that it takes for the satellite''s field of view (image swath) to advance a distance corresponding to the width of one resolution element of the image dissector. The resulting output video information from the image dissector camera tube is then encoded, along with satellite altitude information, onto a transmitted carrier frequency. At the ground receiving station, the video information is decoded and is then transformed, by suitable electro-optical transducer means, into a visual display on a drum recorder or a cathode ray oscilloscope, for example. The proposed television system of the present invention also includes means for compensating or rectifying the video display to account for curvature of the earth.，下面是Television satellite system专利的具体信息内容。
