COMS 1 (Communication, Ocean and Meteorological Satellite) is a South Korean communications, oceanography - and Meteorology Satellite .
COMS 1 was launched on June 26, 2010 at 21:41 UTC together with Arabsat 5A with an Ariane 5 ECA and placed in geostationary orbit at the position 128.3 ° East. It was commissioned by the Korea Aerospace Research Institute (KARI) and built together with Astrium on the basis of the Eurostar E3000 S satellite bus . The satellite, which weighs 2460 kg when launched, has a multispectral imaging system supplied by Astrium for meteorological studies and provides information on weather phenomena on the earth's surface or atmosphere (such as strong storms and precipitation, sandstorms, typhoons, etc.) and the cloud cover. The instrument has five channels, one with a resolution of one kilometer in the optical range and four others with a resolution of four kilometers in the infrared range. Another imaging system is used specifically to examine the sea surface. In eight different spectral bands z. B. Gain information about the chlorophyll content of the water and the occurrence of schools of fish from the geostationary orbit. The instrument reaches a resolution of 400 m.
The third main instrument is an experimental radio system in the S or L band, which collects weather information and broadcasts it worldwide in internationally common data formats. In addition, there are Ka-band - transponder on board which was from the South Korean Research Institute of Electronics and Telecommunications, ETRI (Electronics and Telecommunications Research Institute), developed and will be implemented by, among others multimedia services.
The energy is supplied via a solar cell panel with a span of 17.2 m and an output of 2.5 kW (BOL). The planned service life is 10 years.
