The 23.5° east orbital position was first occupied by the DFS-Kopernikus 1 and DFS-Kopernikus 3 satellites, launched in June 1989 and October 1992, respectively, to provide channel feeds to German cable headends for Deutsche Bundespost (later, Deutsche Telekom).
Astra 3A is one of the Astra communications satellites owned and operated by SES, launched in 2002 to the Astra 23.5°E orbital slot providing digital television and radio for DTH and cable, multimedia and interactive services, corporate networks, and occasional and other business services to central Europe.
