GPS at the
Remote Sensing and GIS lab
What is GPS?
Global Positioning System (GPS) is a satellite-based positioning system
operated by the U.S. Department of Defense. The NAVSTAR satellites are orbiting
the earth every 12 hours and provide worldwide time and position information
around the clock. You need a GPS
receiver in order to receive the signals from the satellites and get your
present geographic position.
