Car navigation allows an automobile driver to see where he or she is on a map at any given time. Automobile navigation can rely on GPS (Global Positioning System), or it can be DVD- or data-based. GPS-bsed navigation uses radio signals from special satellites that send their position and the time of transmission. The GPS receiver catches the signal and calculates the time. The GPS can then calculate the distance from the satellite with the well-known radio signal speed.
