Global Positioning System (GPS) serves as a worldwide radio

U.S. Department of Defense. GPS is a satellite-based navigation
system comprised of 24 orbiting satellites. GPS works on the
principle th
at if you know an object’s distance from several
known locations, you can then calculate its location. The
“known” locations are the GPS satellites, and the distance to
the object is measured using the transit time of an encoded
signal. The satellites also broadcast a data stream along with
the encoded signal to transmit information about their
location.
