When you get in your car, ready to drive to some distant place where you have never gone before, there are some things you need to have with you. These things include supplies, like food and water, clothes, fuel and last but not least, a GPS receiver.

Those little devices that you can fit in the palm of your hand are very handy when it comes to finding the best route to your destination. A GPS receiver is any device that can help you pin-point your location anywhere around the world, day or night.

But how does a GPS receiver work? Even though this may come as a shock to you, but at the basis of the whole concept stand highly accurate atomic clocks. These things can provide all the necessary information needed by the consumer or beneficiary.

To obtain the results a constellation of satellites are used, between 24 and 32 in numbers. The satellites emit microwave signals, and calculating the time it takes to get to the GPS receiver, these things can determine the location, time and velocity.

About four satellites are used to obtain each result. This is because each of the satellites emits a signal that propagates as a sphere. When three of these spheres intersect, that is the location of the receiver. The result from the fourth satellite is used to correct any errors than may be encountered along the way, and rest assured that huge errors may occur for any result.

The global positioning system was developed by the United States Department of Defense. It was a project developed to aid the air force with their GPS tracking systems, but after an unfortunate accident that occurred in 1983, Ronald Reagan released the GPS for the general public. Since then there are many fields that have benefited from this development.

Using the GPS tracking systems, people can now create highly accurate maps of unknown areas around the world. Thus people will have a helping hand when they go exploring new territories, minimizing the probability of getting lost.

Commercial use of GPS can be found in many vehicles. They can be incorporated with the car, or they can be bought separately, as a small device that can display all the information you need. Using the GPS tracking systems, you can determine which the fastest route to your destination is, you can record a route you use or you can benefit from all the other features this device has to offer.

When you set out to buy your own GPS device, then you are in for a treat. There are lots of places where you can buy them from, lots of brands you can choose and lots of tracking systems with various features that can appeal to you.

The question is which the best one is. In order to find the best solution for your dilemma, you should visit the website findritegps.com. Here you will find a wide collection of models from the best brands, and you are bound to find the right GPS receiver for you.
