DIRECTV 11

Mission Profile

Lifting off from the Odyssey Launch Platform at 154 degrees West Longitude, a Zenit-3SL rocket placed the DirecTV 11 satellite into Geosynchronous Transfer Orbit, with the spacecraft separating from the upper stage at 2130 km (1,323 miles) above the Indian Ocean.

Two-and-a-half minutes after liftoff, the first stage and then the payload fairing jettisoned. Five minutes later, the second stage separated from the Block DM upper stage. After the first burn of the Block DM, the spacecraft and the upper stage coasted for 30 minutes over the Pacific Ocean, South America and the Atlantic Ocean. Following this coast, the Block DM executed a second burn for about seven minutes and then coasted again for about ten minutes until spacecraft separation over the Indian Ocean. Boeing Satellite Systems acquired a signal from the spacecraft at a ground station in Hartebeesthoek, South Africa nearly six hours later.

With a designed lifetime of 15 years, the satellite will ultimately be positioned in Geostationary Orbit, 35,786 km (22,236 miles) above the Earth, at 99.2 degrees West Longitude.
