From its ocean-based launch site located directly on the equator at 154 degrees West Longitude, a Zenit-3SL launch vehicle will lift the 5,600 kilograms (12,345 lbs.) Intelsat 19 spacecraft into an optimized geosynchronous transfer orbit.
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 2:30 minutes after liftoff, and the protective payload fairing will be jettisoned 79 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 5:06 minute operation and then shut down for a 30 minute coast period. The Block DM-SL will burn a second time for 6 ½ minutes. Following this second burn, and another 9:50 minute coast period, the spacecraft will separate from the upper stage over the Indian Ocean.
