Marine Observation Satellite-1 (MOS-1) is scheduled for launch in the January and February period of 1987. Main objectives of the MOS-1 are to observe the sea, land and atmosphere by three radiometers (MESSR, VTIR and MSR) and to develop fundamental technologies for earth observation system consisting of space and ground segments. In order to accomplish these objectives NASDA is developing both MOS-1 and ground facilities, and NASDA conducted MOS-1 airborne verification experiment to develop various algorithms which were converted into MOS-1 data processing facility and then used in MOS-1 verification program (MVP). The purposes of the MVP are to evaluate and confirm the distortion correction methods and performance evaluation methods, to evaluate effectiveness of parameters of MOS-1 mission equipment and to reflect the results of the evaluation on the development and operation of the future earth observation system. Concerning radiometric performance, correction methods of deviation of CCD sensitivity for MESSR, calibration methods for VTIR and MSR have been developed and evaluation methods of S N and dynamic range have been studied. Concerning geometric performance, geometric distortions are classified and distortion correction methods have been developed. Moreover, spatial resolution have been evaluated. In this paper, some of the geometric and radiometric performance evaluation methods are presented and evaluated.
