GPS receivers are devices that get signals from orbiting satellites in order to determine the location or geographic position. The applications of the Global Position System technology are very large, with GPS receivers functioning for the aviation, the marine, the military and the average consumer. The satellites on which the receivers depend circle the globe twice a day, and they are arranged in such a way on the orbit, that at any moment of the day, four of them should be present on the visible sky allowing one to find the right location or direction. The US military was intended to be the primary beneficiary, but the system and all of its applications were opened to the public after a while.

In terms of structure, you can choose between two types of GPS receivers: the stand alone GPS receivers and the items that require computer connection in order to function. The stand alone devices insure great mobility, being designed for cars mainly. Such GPS receivers include a pre-installed software with interactive street maps, route info, and minute details on routing directions. For certain regions, you can also get information on points of local attraction with the GPS devices. Some of the best sold products in this category are manufactured by Navigon, Garmin, TomTom, Mio or Magellan Navigation.

The devices that do not function independently require connection to a laptop, computer, PDA or smartphone. Such GPS receivers can be connected either by cables or by Bluetooth technology. You may have to get the navigation software separately from the GPS unit, because less advanced devices do not have it included. Although these GPS receivers seem to be more difficult to work with in the first place because of the installation, they are nevertheless preferred by users because they are cheaper.

While our ancestors had to read the stars to find their way, we can now manage to travel in the urban jungle and all over the world with automatic assistance from GPS receivers. Not all devices come with full world maps, particularly if you buy GPS modules. The Google Maps program can be used for downloading data for a certain geographical area or country. Geo-spatial orientation will no longer be a problem when you have such a travel companion to tell you the best and fastest way to get to destination without the trouble of getting into traffic jams.
