Eutelsat 33C
Eutelsat 33C (formerly Eurobird 1 and Eutelsat 28A) is a Eutelsat operated Eurobird satellite, used primarily for digital television. It was launched in March 2001, and after a short period testing at 33°E, joined Eutelsat 2F4 at 28.5°E in the Clarke Belt, just within the range of satellite dishes pointed at SES' Astra 2 satellites at 28.2° east. It moved to 33° east and joined Eutelsat 33B in July 2015.
==Operations==
The satellite has three beams. A fixed beam covers almost all of Europe as well as north-western Africa. There are also two steerable beams - the first, "S1", co-focused with the fixed beam but with a Europe-only footprint, and a second, "S2", aimed to central Europe. This beam features many transponders with low symbol rates, used for satellite news gathering.
It features 24 active transponders and 12 backup transponders, all Ku band. 12 of its transponders are significantly wider (72 MHz 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.〔(''Eutelsat 28A at 28.2°E'' ) IMS. Accessed July 3, 2015〕
