Abstract: The techniques of digital close-range photogrammetry were successfully used in the high-low temperature deformation measurement of satellite antenna’s reflector in thermal vacuum, and problems of traditional measuring methods that can not be conducted in the vacuum environment were overcame. Excitingly, the measuring precision of the new method with two 8-megapixel digital cameras contained in custom-made pressurized canisters could reach 0.1mm, and could satisfy the designing requirements of products.

Key words: Satellite antenna, Thermal-vacuum distortion measurement, Digital close-range photogrammetric survey, Flatness, Camera canister
