The Air Force is set to launch the seventh GPS IIF satellite this Friday.

An Atlas V 401 will launch the GPS IIF-7 mission for the U.S. Air Force on Friday, August 1, from Space Launch Complex (SLC)-41 at Cape Canaveral Air Force Station, Florida. The 18-minute launch window opens at 11:23 p.m. EDT.

live webcast of the launch will begin at 11:03 p.m. EDT. To keep up to speed with updates to the launch countdown, dial the ULA launch hotline at 1-877-852-4321 or join the Facebook conversation and follow UA on Twitter using the hashtag #GPSIIF7.

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 Air Force Second Space Operations Squadron indicates that IIF-7, SVN-68/PRN-3, will replace SVN-43 in the F plane slot 3 (F3).  SVN-43 will be re-phased from F3 to the F2F slot to replace SVN-26.  SVN-33 will be taken out of the operational constellation the day after SVN-68 launch and sent to Launch, Anomaly and Disposal Operations (LADO).

SVN-33 was launched on April 9, 1996, successfully serving over 17.5 years, 10.5 years beyond its design life. SVN-26 will back-up SVN-43 once it completes its re-phase journey.
