Eutelsat Hot Bird 13B (formerly: Hot Bird 8 ) is a commercial geostationary communications satellite owned by Eutelsat .

development

The satellite was commissioned by Eutelsat from EADS Astrium in September 2003 as Hot Bird 8 . It was built on the basis of the “Eurostar 3000” satellite bus and has a planned service life of 15 years. Hot Bird 8 was the largest and most powerful satellite that Eutelsat had ordered up to that point. It has 64 Ku-band transponders that can transmit 950 TV and 550 radio programs. The solar cells for power supply have a span of almost 40 m.

EADS Astrium supplied two more identical satellites under the names Hot Bird 9 and Hot Bird 10 , which are now named Eutelsat Hot Bird 13C and Eutelsat 33E and are positioned at 13 ° East and 33 ° East.

business

The satellite was launched on August 4, 2006 at 21:48 UTC (August 5, according to local time) from the Russian spaceport Baikonur in Kazakhstan. A Proton -M rocket with a Briz-M upper stage served as the carrier . The takeoff weight was 4875 kg.

After take-off and some orbit maneuvers, the satellite went under intensive tests at the positions 1.7 ° East and 4 ° East, then it was brought to its final position at 13 ° East . On October 3, 2006, all programs from the Hot Bird 3 satellite located there were switched to Hot Bird 8, which started commercial operations and Hot Bird 3 could then be moved to 10 ° East.

When Eutelsat changed the naming system of the satellites on March 1, 2012, Hot Bird 8 was named Eutelsat Hot Bird 13B according to its orbital position.

Disturbance from Iran

The government in Iran apparently tried several times in early 2010 to disrupt the satellite's broadcasting operations. Among other things, the Persian services of the BBC and Voice of America , as well as the Arabic program of Deutsche Welle were affected . For this purpose, a jammer sent a strong signal on the frequency of the Usingen earth station , from which the satellite, then still called Hot Bird 8, received its programs. Thanks to the Sat-ID software , Eutelsat employees were able to identify the city of Tehran in Iran as the source of the interference signal. For a while, the affected programs were broadcast via other satellites which could not be reached by the interference signal.
