GPS IIF Constellation

Boeing and the U.S. Air Force on February 5, 2016 completed the GPS IIF constellation with the launch of the 12th Boeing-built satellite. Following on-orbit tests, GPS IIF-12 will be formally declared operational in approximately one month, making it the 50th GPS satellite Boeing will have delivered on orbit to the U.S. Air Force.

Since the first launch on May 27, 2010, the GPS IIFs have advanced the U.S. Air Force’s Global Positioning System (GPS) modernization program by improving accuracy and security while introducing new civilian and military capabilities to a system used by millions of people around the world.

«This GPS IIF milestone builds on our 40-plus years of GPS experience and a strong Government-Boeing partnership», said Dan Hart, vice president, Boeing Government Satellite Systems. «We continue investing in GPS innovation while driving down costs, keeping GPS prepared to meet current and future demands».

Boeing has been the prime contractor for GPS since the program’s inception, providing multiple generations of satellites that have collectively accrued more than 540 years of on-orbit operation.

GPS IIF-12 lifted off from Cape Canaveral U.S. Air Force Station aboard a United Launch Alliance (ULA) Atlas V launch vehicle at 8:38 a.m. EST. About three hours and 23 minutes later the spacecraft was released into its medium Earth orbit of about 12,000 miles/19,312 km. Signal acquisition was confirmed at 12:09 p.m. EST.

Boeing and its heritage companies have been advancing satellite technology for more than 50 years. Continuing investments in space are helping the company retain its industry leadership as it begins its second century in 2016.

Modernization for GPS

The 10th Boeing GPS IIF satellite has reached orbit and sent its first signals after being launched on July 15, 2015. This satellite advances the U.S. Air Force’s modernization program for GPS, improving accuracy and enhancing security for the navigation system used by millions of people around the world every day.

The Boeing-built GPS IIFs are the newest generation of GPS satellites, delivering a longer design life, greater accuracy, increased signal power for civil applications, a more robust military M-code signal and variable power for better jamming resistance. The IIFs also are outfitted with the new civilian L-5 signal, which, when fully operational, will be used for emergency applications.

«The GPS IIF-10 launch milestone continues a series of recent unparalleled successes for the GPS IIF program», said Dan Hart, vice president, Boeing Government Space Systems. «We understand the importance of this system to the global community, both civil and military, and the government-Boeing team is partnering to assure mission success and operational excellence».

GPS IIF-10 lifted off from Cape Canaveral Air Force Station aboard a United Launch Alliance Atlas V expendable launch vehicle at 11:36 a.m. EDT. About three hours and 23 minutes later, the spacecraft was released into its medium earth orbit of about 12,000 miles/19,312.1 km.

Boeing will support the U.S. Air Force in performing on-orbit checkout of GPS IIF-10 before it is formally declared operational in about one month. The next GPS satellite, GPS IIF-11, was shipped to Cape Canaveral on June 8 in preparation for the third and final IIF launch of 2015 later this fall.
