    The Global Positioning System (GPS) is a space-based radio-navigation system consisting of a constellation of satellites broadcasting navigation signals and a network of ground stations and satellite control stations used for monitoring and control. Currently 31 GPS satellites orbit the Earth at an altitude of approximately 11,000 ...

    GPS satellites fly in circular orbits at an altitude of 10,900 nautical miles (20,200 km) and with a period of 12 hours. The orbits are tilted to the earth's equator by 55 degrees to ensure coverage of polar regions. Powered by solar cells, the satellites continuously orient themselves to point their solar panels toward the ...

    The GPS satellites are uniformly distributed in a total of six orbits such that there are four satellites per orbit. This number of satellites and spatial distribution of orbits insures that at least eight satellites can be simultaneously seen at any time from almost anywhere on Earth. The GPS satellites circle the Earth at an ...

    How far do GPS satellites fly?GPS satellites fly in medium Earth orbit (MEO) at an altitude of approximately 20,200 km (12,550 miles). Each satellite circles the Earth twice a day. Expandable 24-Slot satellite constellation, as defined in the SPS Performance Standard.
    How many GPS satellites are in orbit?The U.S. federal government is committed to providing a minimum of 24 operational GPS satellites in orbit, 95 percent of the time. There are currently more than 30 satellites up, providing some margin for error. Air Force Colonel, Bradford Parkinson, was the lead architect for the Global Positioning System (GPS) program.
    How does a satellite orbit the Earth?As the satellite moves, the Earth rotates underneath it. In 24-hours, the satellite crosses over the same two spots on the equator every day. This orbit is consistent and highly predictable. It is the orbit used by the Global Positioning System (GPS) satellites. The second common medium Earth orbit is the Molniya orbit.
