The U.S. Air Force launched the most technologically advanced GPS satellite ever developed, the GPS IIR-14, on a Delta-2 rocket at 11:37 p.m. (EDT) from Cape Canaveral Air Force Station in Florida. The GPS IIR-14 was the first of eight satellites planned for the new GPS, which the Air Force had created to provide improved encryption and GPS antijamming capabilities for the U.S. military, as well as an improved GPS signal for civilian users. At the time of the launch, the GPS constellation consisted of 28 satellites, which the Air Force was operating for both civilian and military users.
