SES is one of the world's leading satellite owners and operators with over 70 satellites in two different orbits, geostationary orbit (GEO) and medium Earth orbit (MEO).[6] These include the well-known European Astra TV satellites, the O3b data satellites and others with names including AMC, Ciel, NSS, Quetzsat, YahSat and SES.

Based in Betzdorf, Luxembourg and founded in 1985 as Société Européenne des Satellites, the company was renamed SES Global in 2001 and has been simply "SES" since 2006. The company's stock is listed on the Luxembourg Stock Exchange and Euronext Paris with ticker symbol SESG and is a component of the LuxX, CAC Next 20 and Euronext 100 stock market indexes.

A book, High Above, telling the story of the founding of SES and the development of its first Astra satellites was published in 2010 to mark the company's 25th Anniversary, and was followed by Even Higher in 2012 and Beyond Frontiers in 2016.
