GK-2A launched on December 5, 2018, allows diverse observations with sixteen channels, in comparison with the 5 channels of the former COMS (Communication, Ocean and Meteorological Satellite).
Based on this, 52 meteorological products have been created.
The GK-2A is capable of the observations over the full disk at 10-minute interval providing a wealthy of information more speedily so to detect and prepare for adverse weather occurrences.
GK-2A, equipped with the high-performance weather sensor (AMI) contributes to perform more accurate observations along with high-resolution color image, moreover,
the independent development of the space meteorological payload made the national capabilities in the space meteorological observation area strengthened.
The National Meteorological Satellite Center (NMSC) has developed ground stations to receive, process and serve the observation data from GK-2A ever since 2013. The multiple backup systems serve non-interrupted data in real-time, and the established remote storing system preserves the data.
03. Meteorological products of GK-2A
The 52 types of meteorological products developed by the National Meteorological Satellite Center (NMSC) consist of 23 basic and 29 side products. The description on specific algorithms of the products will be provided on the homepage.
04. Technology development
The NMSC develops and services the technologies with the data receiving from GK-2A to be used in various fields, such as numerical model, typhoon/ocean, weather and environment observation.
05. Ground broadcasting service of GK-2A
The NMSC has established the high performance system to process the enormous amount of data from GK-2A. Using the satellite broadcasting function onboard, the huge real-time processed data, all channel data in original resolution (Ultra high rate information transmission, UHRIT), channel data same as in COMS (High rate information transmission, HRIT) and offshore meteorological information (Low rate information transmission, LRIT) are disseminated to the users of oceans in East Asia.
06. WEB based satellite data service
The NMSC plans to provide information in various fields to the users through WEB, Open API, FTP, DCPC.
07. Expected effects
The use of GK-2A takes effects in various fields, involving the improvement in weather forecast accuracy, enhancing global competitiveness.
