What is a sat nav and how do they work?
With the help of a good sat nav, you'll be able to handle any journey confidently, - spending less time fretting about directions and more time enjoying the open road.
What is a sat nav?
A sat nav is a piece of technology designed to make our time in the driver's seat much simpler and more enjoyable. Typically, sat navs are small, touchscreen devices that can be mounted on your car's windscreen with a sucker pad. When driving, they help you plot your route and provide all the instructions you need along the way, with both on-screen instructions and a friendly voice taking you through the turns you need to make.
How do sat navs work?
Sat navs work by using Global Positioning System (GPS) satellite receivers to calculate your position on earth, which then pinpoint your position to within 10 metres. This is then aligned with up-to-date stored digital maps, so you can see your positioning on a digital road map on-screen. In a nutshell, you tell the sat nav where you want to go, and it will find the best way of getting you there.
