Starting from the signal from orbiting satellites, GPS receivers are able to determine the geographic position or location in real time. There are very diverse applications of the Global Positioning System as the GPS receivers are used not only by the aviation, the marine and the military but by civilian consumers as well. The satellites spin around Earth twice a day, and their number and positioning allow for at least four to be visible at any moment you’d check the sky. 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.

There are two types of GPS receivers available for purchase: the stand alone GPS receivers and the items that require computer connection in order to function. The highest mobility is achieved with the stand alone devices, which perfectly matches car usage. Pre-installed software with route info, routing directions and maps is part of the built-in features of the most advanced GPS receivers. 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. The connection of the two devices together can be established through Bluetooth technology, or with a USB or serial cable. 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.

Thanks to the GPS receivers we now install on our cars, navigation is facilitated at the maximum: we no longer depend on rudimentary orientation instruments but on the most efficient technology. GPS modules will not include world maps, but that is hardly an inconvenience. The Google Maps program can be used for downloading data for a certain geographical area or country. From the avoidance of traffic jams, an increase in fuel economy and travel comfort to the possibility to choose the best routes possible and receive lots of practical information, GPS receivers are trustworthy travel companions that rarely fail.
