What is a GPS? How does it work? The Global Positioning System (GPS) tells you where you are on Earth. Itâs eleven oâclock ... do you know where your kids are? Would you like to? One way to track them would be to have a GPS receiver installed in the car! The GPS, or Global Positioning System, is one of the hottest technologies around, and no wonder. Consider these diverse uses: Minnesota scientists use GPS to study movements and feeding habits of deer.
GPS stands for Global Positioning System. The system is made up of at least 24 satellites orbiting the Earth. The satellites communicate with specialized receivers on the ground, providing the exact position of the receivers. As of this writing, there are 31 operational satellites in the GPS constellation. Put in place by the US military starting in 1989, the GPS satellite constellation transmits a signal for its own use and a separate signal that anyone with the technological wherewithal is free to access.
