Global Positioning System (GPS) (GPS)

A system of satellites and receiving devices used to compute positions on the Earth. GPS is used in navigation, and its precision supports cadastral surveying.

A satellite-based system for recording positional information and other data about a geographic feature. Ground positions are calculated by using signals from satellites orbiting the Earth.

A satellite based device that records x,y,z coordinates and other data. GPS devices can be taken into the field to record data while driving, hiking, or flying. Ground locations are calculated by signals from satellites orbiting the Earth.

A navigation system which uses a constellation of artificial earth satellites to make precise determinations of the latitude and longitude of locations on the earth's surface or in the atmosphere.

The NAVSTAR Global Positioning System is a space-based radio navigation network providing precise positioning and navigation needs of all the military services. In the fully operational configuration, there will be 18 satellites in six orbital planes with an orbit period of 12 hours at 10,900 nautical miles altitude. Each satellite transmits three L-band, pseudo-random noise-coded signals, one S-band, and one ultra high frequency for spacecraft-to-spacecraft data relay.

A US satellite system that lets those on the ground, on the water or in the air determine their position with extreme accuracy using GPS receivers.

A Global Positioning System is a satellite-based radio navigation system developed and operated by the U.S. Department of Defense (DOD). GPS permits land, sea, and airborne users to determine their three dimensional position, velocity, and time 24 hours a day, in all weather, anywhere in the world with a precision and accuracy far better than other radio navigation systems available today or in the foreseeable future.
