The USNO master clocks control GPS timing. They are accurate to within one second every 20 million years (Satellites are so picky! Humans, on the other hand, just want to know if we’re too late for lunch) USAF photo by A1C Jason Ridder.

Air Force Backs GPS OCX as Temporary Shutdown Looms

The Air Force is defending the new GPS ground system, taking a stand against naysayers in Congress and declaring through its actions an intent to stick with the Next Generation Operational Control System program (OCX) — at least for now.

The most public of these actions occurred June 30 when Secretary of the Air Force Deborah Lee James announced OCX would surpass by at least 25 percent the program’s estimated cost. She declared a critical Nunn-McCurdy breach, putting the program on a path to automatic cancellation.

Interference Mitigation in the E5a Galileo Band Using an Open-Source Simulator

Four global navigation satellite systems are scheduled to be fully operational orbiting Earth in the coming years: the NAVSTAR Global Positioning System (GPS) from the United States, the GLObal NAvigation Satellite System (GLONASS) from Russia, the Compass/BeiDou-2 System (BDS) from China, and Galileo from Europe. A considerably high number of signals, coming from the satellites of those constellations, will share the radio electric spectrum.
