BREVARD COUNTY • CAPE CANAVERAL, FLORIDA – A United Launch Alliance Atlas V rocket is scheduled to launch a GPS satellite into orbit on Friday at 11:23 p.m. from Space Launch Complex 41.
The launch, which is ULA’s ninth this year, has an 18-minute window.
“The ULA team is proud to be the launch provider for the U.S. Air Force (USAF) Global Positioning System (GPS) Directorate by delivering replenishment satellites aboard Atlas V and Delta IV launch vehicles,” said Jim Sponnick, ULA Vice President of Atlas and Delta Programs.
“GPS IIF-7 is one of the next generation GPS satellites, incorporating various improvements to provide greater accuracy, increased signals, and enhanced performance for users.”
The spacecraft is one of a “constellation of satellites that provides navigation data to military and civilian users worldwide.” There are currently 24 operational GPS satellites.
The Atlas V rocket consists of a booster fueled with highly purified kerosene and liquid oxygen and a Centaur upper stage that uses liquid hydrogen/liquid oxygen to propel the spacecraft into a semi-synchronous circular orbit.
If successful, the GPS satellite will reach orbit after a flight of about 3 1/2 minutes.
This is the 47th launch of an Atlas V rocket.
