Abstract
Korea Ocean Satellite Center (KOSC) has developed the Geostationary ocean color
imager-II (GOCI-II) with Korea Aerospace Research Institute (KARI) and Airbus D&S since
2012 and the GOCI-II Ground Segment(G2GS) since 2015. GOCI-II is assembled to the
Geo-KOMPSAT 2B satellite and finished all functional tests in satellite level before launch
and waiting to move to launch site. G2GS has composed 6 subsystems and it is distinguished
3 operational environments. All G2GS functions are developed for real time data processing
and service of GOCI-II. Also, KOSC has establishing new operational facility including data
receiving antenna in Busan, Korea.
GOCI-II will be launched in March 2020. The In-Orbit Test (IOT) of GOCI-II in KARI
site will be performed to check its functionalities and performances during 6 months after its
successful locating at geostationary orbital position. The radiometric calibration parameter
tuning for the TOA radiance retrieval is planned in this IOT period. Also, the geometric
correction parameter tuning, and validation will be performed simultaneously. To derive
GOCI-II Level 1B geometric corrected data, we adopted the image navigation and
registration methods using star and shore-line observation for keeping geometric correction
error within 2 pixels. After that, KOSC will perform the G2GS IOT for evaluating the G2GS
systems and for calibration and validation of level 2 data gener
