차세대 정지궤도 해양관측위성(GOCI-II) 개발 계획

Abstract

GOCI, the world’s first ocean color observation satellite in geostationary satellite, will be launched on June 2010. Development of GOCI-I took about 6 years, and its expected lifetime is about 7 years. The mission and user requirements of GOCI-II are required to be defined at this moment. Because baseline of the main mission of GOCI-II must be defined during the development time and early operational period of GOCI-I. The main differencebetween these missions is the global-monitoring capability of GOCI-II, which will meet the necessity of the monitoring and research on climate change in the long-term. The user requirements of GOCI-Ⅱ will have higher spatial resolution, 250m×250m, and 12 spectral bands to fulfill GOCI-I’s user request, which could not be implemented on GOCI-I for technical reasons. A dedicated panchromatic band will be added for the nighttime observation to obtain fishery information. GOCI-II will have a new capability, supporting user-definable observation requests such as clear sky area without clouds and special-event areas, etc. This 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 daily is planned for GOCI-II.
