With reference to GOES-9 5-channel Imager and use of 5000-by-5000 pixels areal array CCD and 1000-by-1000 pixels IR FPA, a conceptual design of a staring optical remote sensor for the Geostationary Orbit Satellite has been carried out, and the characteristics that this sensor can reach is discussed and compared with the reference sensor, the results demonstrate that the staring sensor is superior to the scanning-type sensor in the aspect of mass, power assumption, viewing efficiency, frame refresh duration, etc..
