GPS in-car Satellite Navigation Systems

GPS in-car Satellite Navigation Systems have now reached the point where they are incredibly accurate, reliable and easy to use. Maps are available of Europe, North America, Australia, New Zealand, with more being written every year. Unfortunately for the buyer the choice of which one to buy can be very difficult - there are several major players in the market, and dozens of minor ones. Where do you start? A good place is reading our reviews and guides. In each review we try to be as honest as possible to you, the purchaser, and give the best advice about which one to buy.

Car GPS navigation systems feature effortless touch screen operation and an easy-to-use interface for the ultimate convenience. Enter an address or place name, and your GPS shows how to get there with clearly marked routes and turn-by-turn directions. You even have the option of enabling vocal directions for completely hassle-free navigation. Your in dash navigation system will recalculate your route if you miss a turn, getting you right back on track. Most car GPS models also include point-of-interest mapping, helping you locate gas stations, stores, restaurants, and other attractions.

Basically, with the use of a car radio receiver, i.e. a device which receives signals from the GPS satellites that orbit the Earth, you can locate yourself or the position of a vehicle for that matter anywhere on the Earth. Assuming of course, that the area you are trying to locate is covered by the GPS satellites. So in other words GPS tracking and receiving simply consists of buying a receiver, popping in some batteries, turning it on and if you have done everything right, the co-ordinates of where you are should appear on your GPS device.
An automobile GPS Navigation System requires a GPS receiver and a map database. Some systems also have drive train sensors to supplement when GPS signals are blocked for brief periods. So what is GPS you are wondering or perhaps you already know and are just looking for a refresher course?
