. Upon its entry into service, prior to becoming part of Eutelsat's Hot Bird fleet, the Hot Bird 10 satellite was used to cover two orbital positions for satellites still awaiting launch. In 2009 it was temporarily renamed Atlantic Bird 4A, and placed at a longitude of 7 degrees west ahead of the September 2011 launch of Atlantic Bird 7. During this time, some of the transponders aboard the satellite were leased by
