Eurobird 1 is a Eutelsat operated satellite, used for digital television. It is located at 28.5 degrees east in the Clarke Belt, just within the range of most satellite dishes pointed at SES Astras Astra 2A, 2B and 2D at 28.2. It was launched in March 2001, and after a short period testing at 33E, joined Eutelsat 2F4 at 28.5E August 3 is the 215th day of the year in the Gregorian Calendar (216th in leap years), with 150 days remaining. ... 2001: A Space Odyssey. ...

The satellite has three beams, one fixed, covering almost all of Europe as well as north-western Africa, although carrying only United Kingdom and Republic of Ireland targeted channels, and two steerable - the first, "S1", co-focused with the fixed beam but with a Europe-only footprint, and a second, "S2", originally aimed to centreal Europe although likely currently co-aimed with fixed and S1. This beam features many transponders with low symbol rates, and is used for 2-way Satellite internet services provided by British Telecom, Tiscali and Digiweb with uplink speeds up to one megabit and downlink speeds up to 4 megabits. In telecommunication, the term transponder (sometimes abbreviated to XPDR or TPDR) has the following meanings: An automatic device that receives, amplifies, and retransmits a signal on a different frequency (see also broadcast translator). ...

Once stationed at 28.5E, the satellite was promoted as providing satellite coverage for all of Europe, and featured both analogue and digital television and radio services serving Austria, the Czech Republic, Slovakia and other countries. Many of the services it carried had previously been on Kopernikus 2 which had operated at 28.5E since 1990. These stations slowly started to leave, mostly due to viewers/listeners in those target audiences moving to more traditional orbital positions - 19.2E for Austria, and the relatively new 23.5E for the Czech and Slovak Republics. Additional demand for bandwidth at 28E, to carry HDTV signals, is likely to lead to S2 having its frequency plan re-arranged so as to allow Sky Digibox receivers to see its transponders. High-definition television (HDTV) means broadcast of television signals with a higher resolution than traditional formats (NTSC, SECAM, PAL) allow. ... The Digibox is a device marketed by Sky Television in the UK to enable home users to receive digital satellite television broadcasts (satellite receiver). ...

It features 24 active transponders and 12 backup transponders, all Ku band. 12 of its transponders are significantly wider (72Mhz bandwidth) than traditional broadcast satellites, and are reconfigurable into multiple "virtual" transponders. Each transponder is fixed only in its polarity, and many are carrying at least two, and up to 6 virtual transponders. The Ku band (kay-yoo kurz-under band) is a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 11 to 18 GHz. ...
