SES Astra is a brand name for a group of geostationary communication satellites owned and operated by SES S.A., a global satellite operator based in Luxembourg. SES Astra satellites are used for broadcasting video, data, and voice services to Europe, Africa, and the Middle East. As of July 2023, there are 11 fully-operational Astra satellites and another 5 as backup/reserve, the majority in five orbital locations - Astra 19.2°E, Astra 28.2°E, Astra 23.5°E, Astra 5°E, Astra 31.5°E. The satellites have a lifespan of approximately 15 years and operate at an altitude of about 35,786 km (22,236 mi) in geostationary orbit
Eutelsat is a European satellite operator headquartered in Paris, France. Eutelsat operates a fleet of satellites that provide fixed and mobile broadband, data, and video services to Europe, Africa, the Middle East, Asia, and the Americas. As of July 2023, Eutelsat has 25 operational satellites in various orbital positions, ranging from 7/8° West to 174° East. The satellites have different lifespans depending on their design and mission, but typically last between 10 and 18 years. Most of Eutelsat’s satellites are in geostationary orbit at an altitude of about 35,786 km (22,236 mi), except for Eutelsat Quantum, which is in a geosynchronous orbit at an altitude of about 36,000 km (22,369 mi) and can change its orbital position and coverage
WorldSpace was a satellite radio network that operated from 1990 to 2008. It was founded by Noah Samara, an Ethiopian-born entrepreneur, with the vision of providing digital audio and multimedia services to developing countries. WorldSpace launched two satellites, AfriStar and AsiaStar, in 1998 and 2000, respectively. The satellites were in geostationary orbit at an altitude of about 35,786 km (22,236 mi) and covered Africa, Asia, the Middle East, and parts of Europe. WorldSpace offered a variety of channels, including music, news, sports, education, and entertainment, in multiple languages. However, the company faced financial and technical difficulties and filed for bankruptcy in 2008. The satellites were decommissioned in 2010 and 2012, respectively
