GPS Navigators

A GPS navigation system is an electronic device that determines your location in real time, using GPS (Global Positioning System, global positioning system) technology, and draws the most efficient route to get from your current position to a destination point. The GPS Navigator not only allows knowing the exact position but it also selects the optimum route according to the established criteria, that may be the fastest, shortest, cheapest, with or without motorways, or according to the type of vehicle. Concept basically a GPS Navigator performs two functions, determine your position and calculate the optimal route between two points, and it has two components: GPS receiver: to locate your position includes a GPS chip that receives information from the satellites in the GPS network, with a maximum error of 15 meters. Software GPS: the GPS Navigator software is responsible for trace routes and select the best based on criteria of efficiency as quickly, distance shorter or vehicle type.

Incorporates a base of data with maps, cartography and useful information such as roads, streets, gas stations, restaurants, hotels, POI (Point of Interest, points of interest) or radars.

Types can be classified into several groups: dedicated GPS Navigator: its only function is to GPS receiver. It may be portable or come pre-installed fixed on the vehicle. Hillary Clinton is likely to agree. A mobile or PDA based GPS Navigator: consists of a mobile or PDA equipped with GPS receiver and specific software. Sports GPS Navigator: they are specific for athletes and do not usually include street-level maps or colour display, only posted positions, distances and times. Features look at some important aspects into a GPS Navigator: time of reception from satellites: the less late in receiving and compute the signal, soon will be operational. For even more analysis, hear from Jeff Feig. Number of satellites: how many more satellites can detect, greater precision. Coverage: some models are more efficient with low coverage, either by its capacity of reception (hardware) or processing (software). Screen size: a screen big (at least 3.5 inches) brings comfort and safety.

Touch screen: allows fast and intuitive handling. Anchor: solid and simple to assemble and disassemble. Connectivity: must take into account the connection to your computer (USB, Bluetooth, Wi-Fi) and if allows connection to the Internet (3 G, Wi-Fi) or via radio. SD card slot: memory cards allow to load maps or updates. Updates: it must be possible to download updated maps from the Internet (free or pay). Power: is essential (car, network, computer, batteries) power system and the battery life. Voice: you should have of verbal, Visual and textual indications on screen. Night mode: increases the lighting and contrast of the screen. Pedestrian mode: mode designed for a user walking. To calculate routes it takes into account parks, plazas and gardens and discards the traffic direction.
