How GPS Receivers Work
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. 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: 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. Pre-installed software with route info, routing directions and maps is part of the built-in features of the most advanced GPS receivers. Some units even allow for updates on the local attractions in certain area. Some of the best sold products in this category are manufactured by Navigon, Garmin, TomTom, Mio or Magellan Navigation.
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. People nevertheless buy these GPS receivers because they are cheaper, although they raise a bit of a challenge in terms of installation.
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. 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.
