GPS navigation device
From Wikipedia, the free encyclopedia
a GPS navigation device is any device that receives Global Positioning System (GPS) signals for the purpose of determining the present location. These devices are used in military, commercial aviation, and consumer product applications.

Some consumer GPS navigation devices feature interactive street maps that may also show points of interest, route information, and step-by-step routing directions. These may be dedicated navigation devices or multi-function devices such as PDAs, smartphones, or laptop computers running GPS navigation software. For examples of these devices see:
Some consumer devices will record trip information for download. This is useful for trailblazing and mapping by hikers and cyclists.
[edit] Commercial Aviation
Commercial aviation applications, such as the Boeing 737, include GPS devices that calculate location and feed that information to large multi-input navigational computers for autopilot, course information and correction displays to the pilots, and course tracking and recording devices.
[edit] Military
Military applications include devices similar to consumer products for small vehicles and ships, and devices similar to commercial aviation applications for aircraft and missles.
