Professional Land Surveyor News: Air Force Upgrades GPS Constellation
SCHRIEVER AIR FORCE BASE, Colo. — The 2nd and 19th Space Operations Squadron will soon take control of the Air Force’s newest GPS satellite following its tentative launch into orbit May 27 from Cape Canaveral Air Force Station, Fla.
The GPS IIF SV-1 satellite represents a substantial upgrade for the GPS constellation. Thanks to improvements with the cesium-based atomic clocks used for timing, the IIF is expected to provide more accurate navigation signals than those of its predecessors.
The new IIF satellite will also broadcast two new signals: a jam resistant military code signal and a third civil signal known as the L5.
This latest addition is part of an ongoing modernization effort for the GPS constellation by the Air Force.
