CURRENT STATUS OF GOCI-II GROUND SEGMENT (G2GS) SYSTEM DEVELOPMENT

Abstract

In 2019, the GOCI-II, second geostationary ocean color sensor of the Republic of Korea, will be launched and its ground segment will be operated regularly. According to GOCI-II specification which is higher than GOCI, we have to develop new ground segment (GS) systems to meet several requirements like timeliness, accuracy, availability, consistency. System development is composed of a. development of data processing algorithms/systems, b. development of ground-based operation systems, and c. development of GS infrastructure. Data processing algorithms are newly developed by applying several bands that have been added to the GOCI-II, and the existing GOCI algorithms will be reused after verification. G2GS systems are developed with six subsystems, data acquisition (DAS), data correction (DCS), data processing (ODPS), data management (DMS), operations and quality management (OQMS), precision correction (PCS). The GS infrastructure will be newly installed in KIOST complex in Busan. The system designed to satisfy the system requirements with the latest IT technologies like automation, parallel processing, optimization, high-performance hardware. The current detailed design has reached the end of the course, completing the interface, screen, component, class, and data diagram design. The system will be finalized in 2018, and tested until launch of GOCI-II. Also, separate data analysis software and data distribution system ground segment (GS) systems to meet several requirements like timeliness, accuracy, availability, consistency.
