GPS Satellite Launch

The U.S. is getting ready to launch it's newest GPS satellite.  Notice that the bird being replaced was launched in 1997.
The United Launch Alliance Delta 4 rocket family will launch a new GPS IIF satellite from Cape Canaveral Thursday night.
Liftoff is scheduled for Thursday at 8:40 p.m. EST, at the start of a 19-minute launch opportunity, according to the United Launch Alliance. The window is timed to deliver the GPS IIF-5 satellite directly into Plane A of the navigation network 11,000 miles above Earth.
GPS IIF-5 will replace the aging spacecraft known as GPS IIA-28 in Plane A, Slot 3 of the constellation. The GPS IIA-28 satellite was launched aboard Delta 249 on November 5, 1997, as the final member of the Block IIA series. It will go into a reserve role in the network for the remainder of its useful life.
