Geostationary Ocean Color Imager(GOCI-I), the world’s first space-borne ocean color observation satellite in geostationary orbit, successfully launched on 27 June 2010(Korea Standard Time). GOCI-I which has been taken about 6 years for the instrument development, has 7.7 years as an expected lifetime. The mission and user requirements of GOCI-II are defined by Korea Ocean Research & Development Institute(KORDI). The main difference between missions of GOCI-I and GOCI-II is the global-monitoring capability of GOCI-II, which will meet the necessity of the monitoring and research on long-term ocean climate change. The user requirements of GOCI- II has higher spatial resolution than GOCI-Is with 250m×250m to fulfill GOCI-I’s user request which could not be realized at the time frame of GOCI-I for technical reasons. It can be achieved by the optimized optics design and state-of-the-art CMOS technology with 7 um pixel. Moreover, additional 4 spectral bands and a dedicated panchromatic band will be added for the determination of Phytoplankton Functional Type(PFT) and enhanced atmospheric correction, and nighttime observation to obtain fishery information respectively. GOCI-II has a new capability, user-definable observation area in local observation mode to fulfill the user requests such as ocean observation over clear sky area without clouds and special-event areas like red tide, green algae bloom, typhoon, and etc. Thses will enable higher applicability of GOCI-II products. GOCI- II will perform observations 8 times daily, the same as GOCI-I’s. Additionally, daily global observation once or twice per day is planned in GOCI-II. In this paper, we present an improved development and organization structure to solve issues that have been emerged during the GOCI-I development. The hardware design of the GOCI-II will proceed in conjunction with domestic or foreign space agencies
