List of geostationary satellites

Eutelsat 33E (formerly Hot Bird 13D, Eutelsat 3C , Hot Bird 10 and Atlantic Bird 4A ) is a commercial geostationary communications satellite owned by Eutelsat .

The satellite is identical to the Hot Bird 8 (now Eutelsat Hot Bird 13B ), which was launched in August 2006, and Hot Bird 9 (now Eutelsat Hot Bird 13C ), which was launched in December 2008. The contract was awarded to EADS Astrium in October 2006.

The satellite was launched by Eutelsat as Hot Bird 10 on February 11, 2009 at 22:09 UTC with an Ariane 5 launcher from the Center Spatial Guyanais rocket launch site (together with NSS-9 , SPIRALE A and SPIRALE B ) into a geostationary transfer orbit. Under the designation Atlantic Bird 4A , it was first positioned at 7 ° West, until it was replaced there by Atlantic Bird 7 . It was then renamed Eutelsat 3C and positioned next to Eutelsat 3A at 3 ° East . On June 19 and 20, 2013, Eutelsat 3D took over the tasks of Eutelsat 3C, which was moved to the Hot Bird position 13 ° East and replaced Eutelsat Hot Bird 13A there on July 4 , which changed to Eutelsat 8 West A , Eutelsat 7 West A , Nilesat 102 and Nilesat 201 on 7 and 8 ° West. In 2016 it was moved to 33 ° East and renamed Eutelsat 33E.

Eutelsat 33E supplies Europe, North Africa, the Middle East and Central Asia with digital TV and radio programs in direct satellite reception.

With the arrival at 13 ° East, the footprint of the other three Hot Bird satellites was adjusted there. Most Hot Bird viewers saw no difference.

At 3 ° East the satellite had an east and a west footprint, which, however, differed only slightly. Both could be received in German-speaking countries with little effort, but more difficult than on 13 ° East. The west footprint (10,950–11,200 MHz horizontal) was only used for feeds , while the east footprint (11,450–11,700 and 12,500–12,750 MHz) also broadcast regular programs, usually from the Middle East and North Africa.
