DATA SWITCHING SYSTEM AND METHOD FOR OVERCOMING RESTRICTION ON DATA OUTPUT SPEED OF LINEAR CCD CAMERA SET IN SATELLITE

摘要

PURPOSE: A data switching system and method for overcoming restriction on a data output speed of a linear CCD camera set in a satellite are provided to allow the camera to carry out its function without deteriorating picture quality of video data or losing video data when the altitude of the satellite is changed or the satellite is tilted. CONSTITUTION: A data switching system includes an FPA(301), a CCD data processor(304), data multiplexers(305) and a switch(306). The FPA is composed of a PAN channel FPA(302) and an MS channel FPA(303) that convert input optical video signals into analog video signals. The CCD data processor tunes the analog video signals. The data multiplexers multiplexes the analog video signals according to an output speed. The switch controls the multiplexed analog video signals to be output as video data.
