Over the past couple of years, the cost of installing a GPS auto navigation system has fallen considerably, and as an inevitable result of this, more and more people are taking advantage of it in order to make it easier to find out where they are going, plan their journeys, and keep track of where they are.

Satellite navigation dates back a lot longer than many people realize. The principles behind SatNav were first tested back in 1967, but it took nearly 30 years before the NavStar GPS System first began operation as a military application in the mid 1990s. Civilian use of GPS navigation was made available soon after the military launch, but the initial costs of using the system were very high, and required ongoing subscriptions to be paid. The first people who took advantage of GPS were pilots, and surveyors, who needed to be able to measure distances with pinpoint accuracy. In the early days , an affordable GPS auto navigation system was out of reach for the average car owner.

Over time, the costs of GPS auto navigation system has fallen considerably, and there are increasing numbers of applications for them and the data that they provide in our daily lives. Manufacturers such as Garmin and TomTom have combined GPS signals Data with existing map information and complex mathematical algorithms to create systems that can be used for navigation on the roads and highways.

These GPS auto navigation systems can be installed into any car in a matter of minutes, and then be used to plan journeys, and keep track of where you are to stop you getting lost on the roads. By being combined with other data, such as traffic news feeds, GPS auto navigation systems can warn drivers about road congestion, and provide alternative routes in real time to ensure that no-one who has such a GPS needs get stuck in a queue again.

There are a number of different styles of GPS auto navigation systems available to suit the needs of the individual, from basic models through to expensive and highly accurate systems able to manage large amounts of data and provide information to the users in order to give feedback about where they have been.

The simplest kind of auto navigation GPS system is a removable gadget that stores the map data internally, and uses a satellite signal to pinpoint the position of the unit. By combining the map data and the satellite signal, routes can be planned, and the user can find their way, while seeing a graphical representation of their route on a small screen. These GPS auto navigation systems can be either removable, or fixed into the car. Many new models actually integrate the GPS into the dashboard, while non fixed systems can either be mounted on the dash, or attached to the windshield using a suction cup.

As well as dedicated auto GPS devices, it is also possible to buy a large number of other gadgets with GPS as a built in feature. Some GPS PDAs can have a GPS module plugged in to them, and used in cars, and an increasing number of cell phones have GPS as a standard feature. On the whole, although these devices have GPS built in, it is not of the same standard as a dedicated system, and wile it may help you know where you are, it will not provide such accurate data or be able to plan routes on the go as well as one of the custom systems from Garmin or Magellan.

At the top end of the list of auto navigation GPS systems, there are a number of fantastic options available. Many of the high end GPS auto navigation systems include a range of features to make getting around as simple and convenient as possible.

Aside from the standard information about maps and positions, these GPS systems can also provide information about local amenities such as gas stations, motels, and even speed control cameras in certain countries. More expensive GPS auto navigation systems come with the ability to upload additional map systems so they can be used in different countries, and through the use of local radio services, provide comprehensive traffic information to the driver wherever in the world he is.

Whether you want a simple auto navigation GPS system to help you avoid the traffic problems in your home town, or are a cross country driver who needs the long distance planning flexibility for getting from a-to-b as efficiently as possible, there is a GPS system available that will suit your needs.
