The 2nd Space Operations Squadron of the 50th Space Wing of the U. S. Air Force, (stationed at Shriever Air Force Base near Colorado Springs), controls the Global Positioning System. They do this with the help of nearly a dozen cesium clocks and three hydrogen maser oscillators, which were originally created to test Einstein's theory of relativity. Twenty-four satellites, along with four spares, circle the planet twice daily, assuring that eight satellites are always in range of any position on the globe.
