Starting from the signal from orbiting satellites, GPS receivers are able to determine the geographic position or location in real time. 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 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. Although initially, the system was planned for the use of the US military alone, it was soon opened to the public for individual, civilian applications.
In terms of structure, you can choose between two types of GPS receivers: a category of devices that require computer connection to function, and stand alone units that do not depend on anything else. 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. Garmin, Magellan, Mio, Navigon or TomTom are the companies that make the best GPS equipment available.
The computer-connected GPS receivers need to be installed on a computer to function, but they also match the mobility needs if used on a PDA, smartphone or a laptop. Such GPS receivers can be connected either by cables or by Bluetooth technology. The disadvantage with this kind of GPS receivers is that they don’t have the navigation software included, and the buyer has to get the program separately. 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.
