Eutelsat W75 / ABS-1B (formerly Eutelsat W76, Eurobird 4, Eurobird 10, Hot Bird 3 ) was a television satellite of the European Telecommunications Satellite Organization Eutelsat , based in Paris.
history
It was launched in 1997 from the Kourou Spaceport as Hot Bird 3 . Until October 2006, Eutelsat operated the satellite under this name at 13 ° East. After commissioning the more powerful Hot Bird 8 in this position, it was moved to 10 ° East in October 2006 in order to co-position it with Eutelsat W1 and renamed Eurobird 10 . On October 4, 2006, there was a drop in performance, which led to a failure of a solar panel.
In March 2007 the satellite was moved to 4 ° East and was named Eurobird 4 . The next shift took place in September 2009 to position 76 ° East, the satellite name was changed to Eutelsat W76 , then followed in November 2009 a small shift to 75 ° East - in the course of the cooperation with Asia Broadcast Satellite (ABS) it became Eutelsat W75 / Renamed ABS-1B , where he worked until June 2011.
The decommissioning took place in July 2011 and the satellite was sent into a cemetery orbit .
Functions
The satellite could be received in Europe , the Middle East and parts of Africa , Asia and Russia . The transmission took place in the Ku band . After moving to 76 ° East, Eutelsat W76 fulfilled a new task for professional services with tracking systems .
