EUTELSAT 3B

Mission Profile

From its ocean-based launch site located directly on the equator at 154 degrees West longitude, a Zenit-3SL launch vehicle will lift the EUTELSAT 3B spacecraft into an optimized geosynchronous transfer orbit on its way to its final geostationary orbit at 3° East longitude.

The Zenit-3SL rocket will begin its ascent phase of flight.  The first stage of the vehicle will separate 2:30 minutes (150 seconds) after liftoff, and the protective payload fairing will be jettisoned 81 seconds later at 3:51 minutes into the flight. The second stage will conduct a 6 minute burn, followed by its separation from the Block DM-SL upper stage.  The Block DM-SL will begin its first of two burns at 8:41 minutes (521 seconds) into the mission, for the duration of 279 seconds.  The upper stage will then shut down for a 30.5 minute coast period, followed by the start of the second burn at 43:50 minutes into the mission.  Spacecraft separation is expected at 1 hour after liftoff, over the Indian Ocean
