Chapter 14 How Does Navigation Work? HWoowrk?Does Navigation Global Positioning System (GPS) In order to navigate you to your destination, your TomTom NAVIGATOR must know where you are now. To find your current position, your TomTom NAVIGATOR uses the Global Positioning System (GPS). GPS is available for free and without subscription. GPS uses satellites to transmit signals to GPS receivers. Using the GPS signal, your TomTom NAVIGATOR can work out where you are and how fast you are going. GPS signals work in all weather, anywhere in the world. Note: Your TomTom NAVIGATOR does not transmit your position, so others cannot use it to track you while you are driving. You can however send your position to TomTom Buddies.
