23:39 Nov. 17 CET;
22:39 Nov. 17 GMT;
17:39; Nov. 17 EST

Launch Site: Baikonur Cosmodrome, Kazakhstan Launch Pad 39

End User: SES SIRIUS, Solna, Sweden

Satellite Manufacturer: Lockheed Martin Commercial Space Systems,Newtown, PA

Launch Vehicle Manufacturer: Khrunichev State Research and Production Space Center, Moscow

Launch Services Provider: International Launch Services, McLean, Va.

Satellite Use: Multi-mission satellite that will provide a wide range of telecommunications services, providing coverage over Europe, Africa and the Baltic/Nordic region.

Satellite Statistics:

52 active Ku-band transponders

2 active Ka-band transponders

Anticipated service life of 15 years

Mission Profile: The Proton launch vehicle will use a 4-burn Breeze M mission design to inject the satellite into a geosynchronous transfer orbit. The first three stages of the Proton will use a standard ascent trajectory to place the Breeze M fourth stage, with the satellite, into a suborbital trajectory, from which the Breeze M will place itself and the spacecraft into a circular parking orbit of 173 km (107.5 miles) inclined at 51.5 degrees. Once the upper stage and SIRIUS 4 are in the parking orbit, the unit will then be propelled into its transfer orbit by a series of additional burns of the Breeze M. Following separation from the Breeze M, the spacecraft will perform a series of liquid apogee burns to raise perigee, lower inclination, and circularize the orbit at the geostationary altitude of 35,786 km (22,236 miles).

Target Orbit at Separation: Apogee: 35,786 km (22,236 miles); Perigee: 7,030 km (4,368 miles); Inclination: 17.3 degrees

Spacecraft Separation: Approximately 9 hours, 13 minutes after liftoff


Coverage will be carried on Sirius 2 5E 12265H 27500 3/4. The test card is already running on the tp :

very good,we must wait ,very long,for this launch,now lets see,how strong ,this special spotbeam would be,thor 5 ,will be also launched,on februry 8
i think sirius 4 ,has also 3 stearable beams,one for central europe,the other for the middle east,and the last,for scandinavian nordic region!
that,could means,that very big antennas,are needed,to catch all beams

colinp

Thanks analoguesat.Just to add launnch is on 17th Nov.
