Afghansat 1 or Eutelsat 48D (formerly Eutelsat 28B , Eutelsat 48B and Eutelsat W2M ) is a television satellite operated by the company Eutelsat (European Telecommunications Satellite Organization).

history

The satellite manufactured as Eutelsat W2M is based on the Indian satellite bus platform ISRO I-3K (I-3000), which was also used in the largely identical satellites INSAT-4A and INSAT-4B . It was built in collaboration between Antrix (a commercial offshoot of ISRO) and EADS Astrium , for which the foundation stone was laid in 2005 through a corresponding contract (final signature February 20, 2006). The payload comes from Astrium, which was delivered to India, where it was installed and tested on the platform.

Eutelsat W2M was brought into geostationary orbit on December 20, 2008 at 22:35 UTC by an Ariane 5 ECA from the Guiana Space Center together with Hot Bird 9 and tested by ISRO. After the end of the tests, during the transfer to the operating position at 16 ° East , a defect occurred in the power supply. On January 28, 2009, Eutelsat announced that the satellite did not meet the operator's requirements for the manufacturer and would not be integrated into the Eutelsat network.

At the beginning of January 2010, W2M was moved to 16 ° East to replace the decrepit satellite Eutelsat W2 , which failed on January 27, 2010. After the Eutelsat W3C, which was launched in October 2011, strengthened the position 16 ° East, W2M could be withdrawn and moved to 48 ° East , where it was named Eutelsat 48B according to the new naming convention . Eventually it was moved to 28.5 degrees East and renamed Eutelsat 28B . However, since it is not allowed to broadcast there, it was moved to 48 ° East in February 2014.
