The KITSAT-1(August, 1992) and KISAT-2(September, 1993) were successfully launched and operated by the SaTReC(Satellite Research Center). Both carry the CCD cameras to monitor the image of the earth. But the analysis of the system has not been carried out so far. So I used the camera bench type automatic equipment in the KSRI(Korea Standards Research Institute) to measure the MTF(Modulaton Transfer Function) value of the lens attached to the CCD camera. I measured the tangential MTF and the sagital MTF varing the f-number and the field angle. According to the result, the light from a point source was imaged in one pixel of the CCD chip when the f-number is smaller than 4.0. And the radiometric analysis of the camera system was carried out.
