차세대 해양관측위성 2호(GOCI-II) 사용자 요구사항 연구

Abstract

After the successful launch and operation of Geostationary Ocean Color Imager(GOCI-I), necessityof succession of GOCI mission, ocean environment monitoring with ocean color, is highly increasinginto international ocean color remote sensing users as well as domestic users in Korea. GOCI, the world’s first ocean color observation satellite in geostationary orbit, was launched on June 2010. As a successor of GOCI-I mission, development of GOCI-II is planned to be started in 2012 andlaunched in 2018. The mission and user requirements of GOCI-II are defined by Korea Ocean Research& Development Institute (KORDI) and international GOCI PI(Principal Investigator)s. GOCI-II will beable to monitor the nearly full Earth disk area centered at 128.2˚E, and to acquire the local area(current GOCI coverage area or user definable area) image with 250m spatial resolution. It is two time better resolution than GOCI. These enhanced features will enable the monitoring and research of long-term ocean environment change with better image quality. The GSD requirement of GOCI- II with 250m×250m at the center of local area was not able to be realized at the development period of GOCI, although many ocean color remote sensing users had continuously requested 250m GSD requirement. Additional 4 spectral bands and a dedicated panchromatic band for nighttime oservation will be added to improve the accuracy of data ping users as well as domestic users in Korea.
