GPS (Global Positioning System) is a joint name for group of satellites that are orbiting around the earth. They were initiated by the US government very long back and made available to public during the Government of President Reagan.

GPS receiver is a petite appliance that transfers and receives signals from satellites that lies within its range. This devices makes sure that users get accurate location details, which actually is provided in the form of pair of co ordinates.

Making use of this information and data you feed GPS, most of the GPS receivers can take users to the destination using a compass like arrow. Development in the technology has enhanced the way users are directed to the destinations. Voice commands are used to inform user well before in time to reduce last minute tensions.

The GPS receiver has now become a very common appliance that is been fitted to security system on sat, mobile phones and more. Digital cameras now come equipped with GPS so that users know where exactly the photo was taken.

On the other hand, Sat nav (Satellite Navigation) is a special software that makes use of GPS signals. It takes help from the GPS device by getting the co ordinates to combine with that of a complete map. When users input a destination, it is this sat nav software that computes route, distance, estimated time to reach and even suggestions of taking better route and so.

The software keeps updating the GPS signal most frequently to provide user step by step instruction stating where you are and the place to need to make a turn. The conclusion; sat nav and GPS have different meaning and do not mean the same.
