A receiver, like you might find in your phone or in your car, is constantly listening for signals from these satellites, which can be used like a giant tape measure between the receiver and satellites. The GPS system helps in tracking and monitoring the movement of an object or person. Each satellite makes a full orbit of Earth every 12 hours. Reference Stations: A network of ground-based reference stations is installed throughout the area in which the DGPS system will be used. A GPS device communicates with 4 or more satellites to determine its exact location coordinates (latitude and longitude) anywhere on Earth.It works in any weather as long as the device has a clear line of sight to the . The Global positioning system tracker is used daily for calculating accurate time measurements, location tracking, navigation, and more. Each satellite has its own internal atomic clock and sends a time-coded signal on a specific frequency. If someone ends up in an emergency situation in a remote area, GPS beacons notify authorities of someone's location and they can be rescued. The GPS identifies the location data and transmits it to the GPS receiver, where it is processed to display relevant information to the user.
