Mission details:

• Multi-mission satellite with three payloads: one for meteorology, one for ocean observation and one for communications.
• Arianespace launched vehicle L552, an Ariane 5ECA, on flight V195 on Jun 26, 2010 from Kourou. The EPC stage flew a -1106 x 212 km x 7.2 deg trajectory, and the ESC-A stage then delivered two satellites to geostationary transfer orbit.
• The Chollian satellite is South Korea's Communications, Ocean and Meteorological Satellite (COMS-1), also a Eurostar E3000 but only 2461 kg mass at launch. In addition to C and Ku band communications systems, Chollian carries a multi-spectral meteorological imager with four 4km-resolution infrared and one 1 km-resolution visible channel, the GOCI 8-band ocean color imager for studies of clorophyll and turbidity in Korean peninsular waters, and an L-band/S-band data relay payload for meteorological data.
• "[Chollian] is composed of 3 letters, Chun - Li - An. (The combined word sounds chollian, by a rule in Korean language.) Chun = thousand (or very large/long etc.);li = a unit of length (10 li is about 4 km); An = view or vision. So the word means "an ability to see out to very long distance (= 1000 li)".
