A GPS navigator is a device that determines its current location on Earth. The global positioning system is used to obtain precise coordinates. Most GPS navigators provide latitude and longitude information for the area. Some devices can also detect the height.
The two main devices of a GPS navigator are the processor (chipset) and the GPS antenna. The first equipment is a microchip that ensures the joint operation of the rest of the elements.
The GPS antenna is the main signal receiving and transmitting device. Usually it is pre-configured to work with the frequencies on which information is transmitted from navigation satellites.
There are several different programs in GPS navigators. BIOS ensures stable operation of device elements. The operating system and software shell are present in the device to facilitate the use of the navigator.
The most common type of navigator is car GPS devices. The main tasks of car navigators are displaying the current location and laying a route to the desired point. As a rule, they are endowed with a relatively large set of additional functions. In this case, we are talking about working with multimedia files, voice control, and so on.
Tourist GPS-navigators are a miniature copy of car analogs. In addition, these devices have a shockproof housing. The main advantage of this type of navigator is its relatively powerful antenna, which allows it to receive a signal in hard-to-reach areas.
There are also sports navigators. They are usually made in the form of wristwatches. These devices are designed to track the current state of the athlete's body. Naturally, these GPS navigators also display the parameters of a person's movement (distance traveled, speed, direction).
Convenient work with the GPS-navigator is provided by the presence of interactive maps. With their help, the equipment can not only determine its location, but also show information about important objects in the vicinity.
