Updating navigation - how does GPS navigation work?

GPS satellites orbit the Earth in medium orbit and transmit radio signals from it. All navigation satellite service providers make their systems available free of charge to the international community. International Civil Aviation Organisation (ICAO) standards and recommended practices have been developed. The GPS service provides users with an accuracy of 7 metres anywhere on the ground. To do this, each of the 31 satellites emits signals that allow receivers to determine their location and time by combining signals from at least four satellites. The GPS satellites have atomic clocks that display extremely precise times. The timing information is recorded in the codes transmitted by the satellite so that the receiver can continuously determine when the signal was transmitted. The signal contains data that the receiver uses to calculate the satellites' positions and to make other adjustments necessary for precise positioning. The receiver uses the time difference between the time the signal is received and the time it is transmitted to calculate the distance from the receiver to the satellite.

With information on the distances to the three satellites and the satellite's position at the time the signal is sent, the receiver is able to calculate its position. To calculate the distances from these three signals, an atomic clock synchronised with GPS is required. However, the receiver does not need an atomic clock when receiving data from four satellites. So the receiver uses four satellites to calculate latitude, longitude, altitude and time.

Why do I need a navigation update?

With Global Positioning System, every object, building and even tree has its own point, and every point can be marked on a map. GPS thus produces highly accurate maps, with every object having GPS coordinates. However, the world is constantly changing: new roads are being built, new houses, objects and even cities. Therefore, all changes must be kept up to date. In order for a navigation device to guide you as accurately as possible towards your desired destination and to make your route as efficient as possible, it is necessary to constantly navigation update the most up-to-date maps.
