COMS LRIT/HRIT SERVICE CHARACTERISTICS

摘要

The COMS (Communication, Ocean and Meteorological Satellite), the first meteorological satellite in Korea, plans to provide user dissemination services, distribution of ground-processed image data and additional data to end-users via the spacecraft in near real-time. Prior to broadcasting through COMS, the meteorological/ocean image data and additional data are formated in the LRIT (Low Rate Information Transmission)/HRIT (High Rate Information Transmission, the end-user data format recommended internationally by CGMS (Coordination Group for Meteorloogical Satellites).In COMS ground systems, the LHGS (LRIT/HRIT Generation Subsystem) performs the LRIT/HRIT formatting and transmission from received data stream via external systems according to the CGMS Global Specification and COMS LRIT/HRIT Mission Specification. This paper provides overview of the COMS mission specific LRIT/HRIT services which will be the first dissemination service of Korea via the meteorological satellite.
