After months of delays, the U.S. Air Force is about to launch the first of a new generation of GPS satellites, designed to be more accurate, secure and versatile.
But some of their most highly touted features will not be fully available until 2022 or later because of problems in a companion program to develop a new ground control system for the satellites, government auditors said.
The satellite is scheduled to lift off Tuesday from Cape Canaveral, Florida, aboard a SpaceX Falcon 9 rocket. It’s the first of 32 planned GPS III satellites that will replace older ones now in orbit. Lockheed Martin is building the new satellites outside Denver.
GPS is best-known for its widespread civilian applications, from navigation to time-stamping bank transactions. The Air Force estimates that 4 billion people worldwide use the system.
But it was developed by the U.S. military, which still designs, launches and operates the system. The Air Force controls a constellation of 31 GPS satellites from a high-security complex at Schriever Air Force Base outside Colorado Springs.
Compared with their predecessors, GPS III satellites will have a stronger military signal that’s harder to jam — an improvement that became more urgent after Norway accused Russia of disrupting GPS signals during a NATO military exercise this fall.
