Abstract

The multispectral camera mounted on ZY-3 satellite has been developed according to the requirements of a mapping camera. Many advanced techniques have been adopted to improve image quality of the camera. An off-axis three mirrors anastigmatic (TMA) telescope with high MTF, low distortion and wide field of view has been developed. High mechanical stability has been achieved by using flexible mounting technique. The radiometric quality of the camera system has been improved by using high integrated and low noise technology of the circuit. Testing in orbit proved that the functions and performances of the camera completely meet to the requirements, and some beyond. The camera intrinsic parameters remain stable. After geometrical testing and correcting, the location accuracy achieves high level. The paper describes the technology of design, fabricating, alignment and tests of the camera. The result will be useful for the other similar cameras.
