Abstract
GOCI(Geostationary Ocean Color Imager), the worlds first ocean color observation imager in geostationary orbit, is one of three main payloads of COMS(Communication, Ocean and Meteorological Satellite). It was successfully launched at Kourou Space Center in French Guiana by Ariane 5 ECA Launch Vehicle in June 27, 2010(KST). In order to detect, monitor and predict the short-term biophysical phenomena, GOCI has six visible bands and two near-infrared bands for the purpose of atmospheric correction. Ground Sampling Distance of GOCI is about 500m at the center of the GOCI coverage area. The size of GOCI coverage area is the 2,500km×2,500km square, and the location of the coverage center is at 36˚N and 130˚E.GOCI coverage area is composed of 16(4x4) slots. Because GOCI equips 2D CMOS with 1413 x 1430 effective pixel array, IFOV of GOCI directly corresponds to FOV of GOCI slot area. GOCI also has been developed to observe the GOCI coverage area by every hour and planned to observe and transmit 8 GOCI coverage area images per day. The mission life time of the GOCI is about 7 years after In-Orbit Test(IOT).During the GOCI In-Orbit Test(IOT) campaign, GOCI functional test to verify the operability of GOCI, and GOCI radiometric test were successfully accomplished. For the moment, GOCI geometric performance test is on-going. In parallel, operation test and verification of GOCI ground processing system equipped in KOSC are on-going without any major issue. In this paper, we present the overall status of GOCI including preliminary results of GOCI IOT.
