From its equatorial launch site at 154 degrees West Longitude, a Zenit-3SL launch vehicle will lift the Galaxy 19 spacecraft to geosynchronous transfer orbit, on its way to a final orbital location at 97 degrees West Longitude. The first stage of the vehicle will separate two-and-a-half minutes after liftoff and the protective payload fairing will jettison 75 seconds later. After operating for six minutes, the second stage will separate from the Block DM upper stage. The Block DM upper stage will then operate for eight-and-a-half minutes. Following a 33-minute coast period, the Block DM will burn a second time for three minutes. After the second burn, and another 10-minute coast, the spacecraft will separate from the upper stage over the west coast of Africa. The Hartebeesthoek ground station near Johannesburg, South Africa, will be tracking the spacecraft to acquire its first signals soon after spacecraft separation.
Built by Space Systems/Loral (SS/L), the 1300-series hybrid spacecraft, with a separated mass of 4,690 kg (10,340 lbs), carries a total of 52 physical transponders. The Galaxy 19 satellite will provide Intelsat customers valuable 50-state coverage, in addition to reaching the Caribbean, Canada and Mexico. An industry leader in power, performance and reliability, SS/L's 1300 model is a space-proven platform for a wide range of satellite services with an excellent record of reliable operation. Its high efficiency solar arrays and lightweight batteries are designed to provide uninterrupted electrical power. Galaxy 19 will be located at 97 degrees West Longitude, replacing G-25.
