Both the words GPS and Gps have gradually crept into everyday use. They can be are often used interchangeably. What is the difference between them and if so, what is the difference?

Firstly, yes we have a difference.

GPS is short for Global Positioning System. It is the collective reputable name a group of satellites that are in orbit around the Earth. We were looking at placed there through the US Government decades ago and created publicly available during the administration of President Reagan.

Using a GPS receiver (a smallish device that can send and receive signals from the satellite within range) you may get your precise location. This location is provided as a set of co-ordinates.

Using these details and the co-ordinates of your destination, many GPS receivers can 'guide' you to definitely the destination employing a compass-like arrow. In theory, if you have the GPS co-ordinates of your residence, using a GPS receiver you could find your way home from even remotest place in the world.

The GPS receiver in to a common item which is fitted to many devices, like your mobile phone or maybe the security system in your car. Many smartphones, just like the iPhone, have a GPS built-in. If allowed, applications can use this information to direct you to definitely, say, the nearest Italian restaurant. Some cameras even have a GPS. They could use it record where exactly the photo was taken.

A sat nav (short for sat nav) is really some special software that uses the GPS signal. It will require the co-ordinates provided by the GPS and combines that with a comprehensive map. Then, given a destination, the sat nav software will calculate a route so you might your destination. Because the GPS signal is consistently updated, the sat nav can give you step-by-step instructions on your location and when you need to make a turn.

TomTom and Garmin are in all likelihood two of the best known brands when it comes to GPS and sat nav equipment. TomTom is a European company, that mainly produces sat nav devices for cars along with software for smartphones. Garmin, and American company, have a much broader product range: many methods from aircraft GPS systems to GPS watches to help athletes improve their performance.
