10/28/2015 - LOS ANGELES AIR FORCE BASE, El Segundo, Calif. -- Air
Force Space Command's Space and Missile Systems Center and its mission
partners are scheduled to launch the 11th Boeing-built Global
Positioning System's GPS IIF satellite aboard a United Launch Alliance Atlas V 401
launch vehicle Oct. 30 from Space Launch Complex 41 at Cape Canaveral
Air Force Station, Fla. The launch window opens at 12:17 p.m. EDT and
will remain open for 19 minutes.
Ten GPS IIF satellites are currently on-orbit and meeting all mission requirements. Of the remaining satellites, GPS IIF-11 is awaiting launch and GPS IIF-12, the remaining IIF-series satellite, is in storage awaiting final processing and preparation for launch on Feb. 3, 2016.
GPS IIF satellites provide improved signals that will enhance the
precise global positioning, navigation and timing services supporting
both the warfighter and the growing civilian needs of our global
economy. GPS IIF provides improved navigational accuracy through
advanced atomic clocks, a longer design life than previous GPS
satellites, and a third operational civil signal -- L5 -- that benefits
commercial aviation and safety-of-life applications.
"The GPS IIF satellites play a key role in our modernization effort to
provide new space-based capabilities for users around the globe and for
decades to come," said Lt. Gen. Samuel Greaves, Space and Missile
Systems Center commander and Air Force Program Executive Officer for
Space. "We have successfully placed into operation 10 in a series of 12
procured Boeing-built space vehicles, and thanks to the exceptional team
of government, industry and launch personnel we are poised to launch
the 11th GPS IIF satellite aboard an Atlas V 401 launch vehicle later
this week," he said.
Operated by AFSPC's 50th Space Wing at Schriever Air Force Base, located
east of Colorado Springs, Colo., the GPS constellation provides precise
positioning, navigation and timing services worldwide seven days a
week, 24-hours a day.
