Input: Passage: When Sky Digital was launched in 1998 the new service used the Astra 2A satellite which was located at the 28.5°E orbital position, unlike the analogue service which was broadcast from 19.2°E. This was subsequently followed by more Astra satellites as well as Eutelsat's Eurobird 1 (now Eutelsat 33C) at 28.5°E), enabled the company to launch a new all-digital service, Sky, with the potential to carry hundreds of television and radio channels. The old position was shared with broadcasters from several European countries, while the new position at 28.5°E came to be used almost exclusively for channels that broadcast to the United Kingdom. Question: What satellite enabled Sky Digital to launch an all new digital service?
Output:
Eutelsat's Eurobird 1
