It was operated by the Korea Aerospace Research Institute, who used it for communication, oceanography, and meteorological observation. COMS-1 was constructed by EADS Astrium, and was based on the Eurostar-3000S satellite bus, bringing together lessons learned from Eurostar satellites and NASA-made GOES satellites respectively. It had a mass of , and carried transponders broadcasting in the D/ E and K bands of the NATO-defined spectrum, or the L/ S and Ka bands of the IEEE-defined spectrum respectively. Its single solar array generated a minimum of 2.5 kilowatts of power. COMS-1 was launched by Arianespace using an Ariane 5 ECA carrier rocket lifting off from ELA-3 at the Guiana Space Centre in Kourou, French Guiana. The first launch attempt occurred on 23 June 2010; the launch was sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
