Location-Based | GPS

The Global Positioning System (GPS) is a constellation of earth-orbiting satellites transmitting signals to give very accurate geographic position information. Most new smart phones include GPS technology. Civilian GPS applications include determining the location ’on the move’ to show what services or people are near. Line of sight constraints can hamper GPS signal reception and, subsequently, location detection. Combining GPS with cellular or Wi-Fi technology to connect to the Internet provides a rapidly expanding market of location-based services.
