Abstract
Geostationary Ocean Color Imager (GOCI) is the one of the three main payloads in Communication, Ocean and Meteorological Satellite(COMS) and successfully launched at Kourou Space Center in French Guiana by Ariane 5 Launch Vehicle in 27 June 2010(KST).During the in-orbit test campaign, GOCI functional test for the performance check of GOCI sub-systems. GOCI radiometric model, the reference internal radiative transfer function of GOCI H/W, was characterized by the GOCI Solar calibration image acquisition. GOCI radiometric linear gains calculated from initial in-orbit solar calibration varies about 5% comparing with the ground test results. For the GOCI in-orbit radiometric calibration, Solar Diffuser and Diffuser Aging Monitoring Device(DAMD) are implemented into shutter wheel of GOCI. Diffuser aging monitoring is operated from GOCI in-orbit radiometric test. In-orbit measured GOCI diffuser aging factor for six months during GOCI in-orbit tests is about 3%. In this paper, we present the initial operation results of preliminary characterization result of GOCI in-orbit solar calibration operated at in-orbit test period.
