Hot Bird 4

 1998-013A

---

Hot Bird 4 was launched in Feb 1998 by an Ariane 42P. Launch mass was 2885 kg, BOL 1770 kg, 1310 kg dry. The bus is 3.6 x 2.3 x 4.0m with a 27.9 m span. Testing at 29E laid Eutelsat's claim to that orbital slot; it then moved to 13E. While at 29E, it was renamed Europestar 1A, regaining the Hot Bird name at the final position. Hot Bird 4's new Skyplex equipment allowed it to receive multiple simultaneous uplinks.

In 2006, HB4 was renamed Atlantic Bird 4A, still within the Eutelsat fleet. In Apr 2006 it was moved to 7W to supplement the Nilesat system and called Nilesat 103 by the Nilesat operators. It was scheduled to be replaced by Atlantic Bird 7.

In 2009 it was moved to 16E and became EUROBIRD 16, later EUTELSAT 16B.
