ATLANTIC BIRD™ 7
From its ocean-based launch site located directly on the equator at 154 degrees West Longitude, a Zenit-3SL launch vehicle will lift the 4,600 kilograms (10,141 lbs.) ATLANTIC BIRD™ 7 spacecraft into an optimized geosynchronous transfer orbit on its way to its final geostationary orbit at 7 degrees West longitude.
Lifting off from the Odyssey Launch Platform, the Zenit-3SL rocket will begin its ascent phase of flight. The first stage of the vehicle will separate 2:29 minutes after liftoff, and the protective payload fairing will be jettisoned 43 seconds later. Following its 6 minute burn, the second stage will separate from the Block DM-SL upper stage. The Block DM-SL will begin a 5:40 minute operation and then shut down for a 37:13 minute coast period. The Block DM-SL will burn a second time for 5:51 minutes. Following this second burn, and another 9:50 minute coast period, the spacecraft will separate from the upper stage over the Indian Ocean.
