Eutelsat's W4 satellite takes ride on first Atlas 3
EUTELSAT NEWS RELEASE
Posted: May 14, 2000
W4 is an important addition to EUTELSAT's extensive satellite system, and carries two specific missions. A total of 19 transponders on the satellite will be switched into a high-power fixed beam over Russia. Sixteen of these transponders, corresponding to the frequencies held by the Russian Federation (the RST-1 / RITM network), will be used for direct-to-home digital television broadcasting by the Russian media group Media Most.
One fixed and one steerable beam, each with six transponders, will be pointed over sub-Saharan Africa where they will be used for a range of services; most particularly digital pay television and broadband Internet access for a major African client.
W4 will be copositioned at 36 degrees East with EUTELSAT's SESAT satellite that was successfully launched on April 17 by a Proton launcher out of the Baikonur Cosmodrome. SESAT's 18 Ku-band transponders are scheduled to go into service next month for a range of business-to-business services that include Internet backbone connections, corporate networks and the EUTELTRACS mobile messaging and positioning service. It will provide coverage of Europe, North Africa, the Middle East and the Indian sub-continent.
The launch of W4 will be broadcast live in digital in-the-clear by HOT BIRD 3 at 13 degrees East (downlink frequency 12.111 GHz; vertical polarization; FEC 3/4, symbol rate 27.5 symbol).
