GPS navigation works by utilizing a network of satellites orbiting the Earth to determine the receiver’s exact location. The GPS device in the OHREX N700 GPS Navigation or any other GPS system receives signals from multiple satellites and calculates the distance to each one. By triangulating these distances, the GPS device can pinpoint the user’s location on Earth. This information is then used to provide accurate mapping, turn-by-turn directions, and real-time tracking for navigation purposes.
