Summary

COMS 1, also known as Cheollian, is a meteorology and ocean monitoring satellite operated by KARI (Korea Aerospace Research Institute). Launched on June 26, 2010, from the Guiana Space Centre using an Ariane 5ECA launch vehicle, it was built by EADSB with a Eurostar 3000 bus and AstroBus-G configuration. The satellite measures 2.8 meters in length and has a diameter of 1.8 meters, with a span of 17.2 meters due to its solar panels. It had a launch mass of 2461 kg and a dry mass of 1500 kg. Equipped with equipment such as the Meteo Imager, Ocean Colour Imager, S-/L-Band transponder, and Ka-band transponders, COMS 1 is powered by deployable solar arrays and batteries. The satellite was designed for a seven-year mission but achieved nine years of operation, fulfilling its purpose in meteorology, ocean monitoring, and experimental communication.
