The Air Force plans to launch a Boeing-built GPS IIF-8 satellite Oct. 29 following the successful launch of the IIF-7 bird just shy of three months ago on Aug. 1.
The 3,950-pound new satellites have a design life of 12 years and will replace II-A satellites, which were launched between 1990 and 1997 and were designed to last about 7 and 1/2 years.
Eleven of those satellites are still in use, including four launched in 1992.
The II-F satellites feature improved anti-jam protection for military users and a new “safety of life” transmitter from aviation users.
