GPS Receiver

Knowing exactly where to go and where you are at any given moment, when on the move, makes the journey safer and easier. Fortunately, this has been made possible by today’s technology ó the GPS or Global Positioning System. Equipped with a GPS receiver, you can easily find your way around. How does this system work? It simply converts signals received from the satellite into directional maps.

GPS receivers are widely used in cars, adventure sports, navigation, etc. They are overall classified into three types: GPS mice, hand-held types and inbuilt in cars. GPS mice, as the name implies, look like a computer mouse. They are connected to different computing devices such as laptops, PDAs, vehicle navigation system, PC, etc. These self-contained receivers do not have displays and require connections to another devices via USB cables.

Next in the category are the slightly bigger, adult-palm-sized, GPS receivers ó the hand-held types. These are designed for adventure sports such as trekking, hiking and other outdoor activities. Most of these operate on lithium batteries. With an accuracy of approximately 8 metres, these GPS receivers are compatible with both WAAS and EGNOS signals. For better performance, they are often aided with external antennas.

The third type, inbuilt car receivers, are of course made especially for cars. Because of their portability, these types of GPS receivers can be easily transferred from one car to another. They perfectly sit on dashboards and windscreens. These receivers particularly guide drivers through unknown roads.
