|
|
|
GPS
|
Refers to the Global Positioning System (developed by the United States Department of Defense) that uses a constellation of 24 to 32 Medium Earth Orbit satellites that transmit precise microwave signals, which enables GPS receivers to determine their current location, the time, and their velocity.
