GPS Navigation System
A navigation system uses satellite positioning and maps to guide the driver.
What is GPS Navigation System?
Built-in systems use the car screen. Live traffic improves routing. Maps need updates. Many systems combine satellite signals with wheel speed and gyroscope data to keep track of position in tunnels. Built-in navigation can feed data to driver assistance, for example to adapt speed before bends. Smartphone navigation via CarPlay or Android Auto is an alternative with frequently updated maps.
How it works
Satellite signals determine the position.
Why it matters for your car
