Arabsat-5A is a Saudi Arabian communications satellite operated by Arabsat. It is used to provide television, internet, and telephone services to Arabia, Africa, and Europe. Arabsat-5A was constructed by Astrium and is based on the Eurostar-3000 satellite bus. It has a mass of 4,800 kilograms (10,600 lb), and carries forty transponders; sixteen broadcasting in the G/H band of the NATO-defined spectrum, or the C band of the IEEE-defined spectrum, and twenty-four operating in the NATO J band or the IEEE Ku band. Its solar arrays are expected to generate around 12 kilowatts of power at the beginning of the satellite's design life, and around 11 kilowatts at the end of it.
