ATLAS V GPS IIF-8 MISSION A 401 vehicle will deliver the GPS IIF-8 satellite to semi-synchronous circular orbit. Liftoff will occur from Space Launch Complex 41 at Cape Canaveral Air Force Station, FL.

The Navstar GPS is a constellation of satellites that provides navigation data to military and civilian users worldwide. The system is operated The ULA team is proud to be the launch provider for the U.S. Air Force and controlled by the 50th Space Wing, located at Schriever Air Force (USAF) Global Positioning System (GPS) Directorate by delivering Base, CO. replenishment satellites aboard Atlas V and Delta IV launch vehicles. GPS IIF-8 is one of the next generation GPS satellites, incorporating GPS utilizes 24 satellites, in six different planes, with a minimum of various improvements to provide greater accuracy, increased signals, four satellites per plane, positioned in orbit approximately 11,000 and enhanced performance for users. miles above the Earth’s surface. The satellites continuously transmit digital radio signals pertaining to the exact time (using atomic clocks) and exact location of the satellites. The GPS IIF series have a design life of 12 The ULA team is focused on attaining Perfect Product Delivery for the years. With the proper equipment, users can receive these signals to calculate time, location, and velocity. The signals are so accurate that time can be GPS IIF-8 mission, which includes a relentless focus on mission suc- measured to within a millionth of a second, velocity within a fraction of a mile per hour, and location to within feet. Receivers have been developed for cess (the perfect product) and also excellence and continuous improve- use in aircraft, ships, land vehicles, and to hand carry. ment in meeting all of the needs of our customers (the perfect delivery).

As a result of increased civil and commercial use as well as experience in military operations, the USAF has added the following capabilities and tech- My thanks to the entire ULA team, including our suppliers, as well as our nologies to the GPS IIF series to sustain the space and control segments while improving mission performance: mission partners­ — the USAF and the Aerospace Corporation — for their hard work and commitment to mission success. – Two-times greater predicted signal accuracy than heritage satellites. – New L5 signals for more robust civil and commercial aviation. Go Atlas, Go Centaur, Go GPS! – An on-orbit, reprogrammable processor, receiving software uploads for improved system operation. – Military signal “M-code” and variable power for better resistance to jamming hostile environments, meeting the needs of emerging doctrines of navigation warfare.

Payload Fairing (PLF) The GPS IIF-8 spacecraft is encapsulated in the 4-m (14-ft) diameter large payload fairing (LPF). The LPF is a bisector (two-piece shell) fairing consisting of aluminum skin/stringer construction with vertical split-line longerons. The vehicle’s height with the PLF is approximately 189 ft.

Centaur The Centaur second stage is 10 ft in diameter and 41.5 ft in length. Its propellant tanks are MISSION OVERVIEW constructed of pressure-stabilized, corrosion resistant stainless steel. Centaur is a cryogenic vehicle, fueled with liquid hydrogen and liquid oxygen. It uses a single RL10A-4-2 engine producing 22,300 lb of thrust. The cryogenic tanks are insulated with a combination of helium-purged insu- lation blankets, radiation shields, and spray-on foam insulation (SOFI).
