GPSReceiver

The Global Positioning System (GPS) receiver is a device that receives signals from GPS satellites orbiting Earth. These satellites transmit time-stamped signals, and the receiver uses the time difference between when a signal was sent and when it was received to calculate its distance from multiple satellites. By triangulating its position based on signals from at least four satellites, the GPS receiver can determine its precise location, including latitude, longitude, and altitude. Modern GPS receivers are compact and can be found in a wide variety of devices, from smartphones and car navigation systems to specialized equipment for surveying and aviation. The accuracy of a GPS receiver can be affected by factors such as atmospheric conditions, signal interference, and the quality of the receiver itself. The system is maintained by the United States government and is freely available for civilian use worldwide.
