Located at 21.5° East, W6 (formerly
W3) is ideal for companies needing to communicate between Europe, North Africa,
the Sahara, the Middle East and the Gulf region. Fine-tuned for professional
communications, the satellite is perfect for applications such as VSAT networks,
broadband Internet and data broadcasting.
With twenty-four simultaneously
active transponders, W6 provides a widebeam coverage of Europe, North Africa,
the Middle East and Central Asia, and a steerable coverage centred over North
Africa, the Sahara and the Mediterranean region.
Like the W2 satellite, ten channels
can be individually configured for operation via either of the two coverages.
The remaining channels are connected to the Widebeam coverage.
This satellite had two name changes.
When it was launched it was called Eutelsat 3F3. That name changed into Eutelsat
W3. Because of the Olympic Games 2004 in Greece the capacity of this satellite
was to small and Eutelsat launched the Eutelsat W3A for this orbit position.
This satellite had another name change because of that. Nowdays the satellite is
known as Eutelsat W6
