August 21, 2019 – A United Launch Alliance (ULA) Delta IV rocket is in final preparations to launch the second Global Positioning System III (GPS III) satellite, nicknamed Magellan, for the U.S. Air Force Space and Missile Systems Center. The launch is planned for August 22 at Space Launch Complex-37 from Cape Canaveral Air Force Station. The 27-minute launch window opens at 7 a.m. MDT.
The Delta IV family of launch vehicles combines design simplicity, manufacturing efficiency and streamlined mission and vehicle integration to meet customer launch requirements. GPS III SV02 will be the 29th and final flight of the Delta IV Medium rocket and the 73rd GPS launch by a ULA or heritage vehicle.
“As we prepare to launch the final Delta IV Medium, we look forward to continuing its legacy through the purpose-built Vulcan Centaur,” said Gary Wentz, ULA vice president of Government and Commercial Programs. “We are proud to continue our strong support of the GPS program with this launch.”
The GPS III system, built by Lockheed Martin, represents the next step in modernization of the worldwide navigation network with a new generation of advanced satellites offering improved accuracy, better anti-jam resiliency and a new signal for civil users.
This mission will launch aboard a Delta IV Medium+ (4,2) configuration vehicle, which includes a 4-meter Payload Fairing and stands at 207 ft. The common booster core for Delta IV is powered by the RS-68A engine, and the Delta Cryogenic Second Stage is powered by the RL10B-2 engine, both supplied by Aerojet Rocketdyne. Northrop Grumman provided the two solid rocket motors.
ULA has a track record of 100% mission success with 134 successful launches.
