The document discusses the global positioning system (GPS), how it works using 24 satellites orbiting Earth that transmit location data, and how receivers can determine location using signals from 3 or more satellites. It also lists industries and applications that use GPS, such as agriculture, aviation, and mapping, as well as different types of GPS receivers for various uses including handheld, vehicle, and space applications. The document concludes with a brief mention of integrating GPS with multimedia functions on phones.
