GPS is a development owned by the United States and is the only fully functioning satellite navigation system today. Thanks to 24 satellites, which move in three orbital planes, it is possible to determine with minimum error not only the location itself, but also the speed of the object at a certain point of time.

Types of GPS navigators are subdivided into larger devices:

Aviation .
Marine .

And in smaller devices:

Automotive
Portable (tourist)
Aviation types of navigators have been used in aviation for quite a long time and are an important component capable of calculating the way, laying the route, calculating the location and distance to airports. Modern devices are so versatile that they can be adapted for ground use and have a number of specially designed functions, such as routing and point memorization.

Naval positioning devices – chart plotters, are stationary types of GPS navigators, replacing the compass and paper maps. They display geographic coordinates and have a basic database of depths, names of ports, islands, bays, dangers (shallows, reefs). Such devices are installed on all kinds of marine transport: ships, boats, steamships, liners and others.

Car navigators are the most widespread and popular devices among drivers. They are convenient in use, practical and functional, with their help it is possible to take the shortest way, to find the right address, to avoid traffic jams, to understand the direction of the city streets. In addition, these types of GPS navigators are equipped with audio – interactive tips, for example, about the upcoming smooth or sharp turns.

Tourist (portable) navigation devices are a godsend for those, who like to go hiking or traveling. The small screen of this type of device displays all the necessary information – route, terrain, altitude. Some devices sometimes include additional functions, such as an electronic compass, fisherman’s, hunter’s calendar, solar and lunar calendars. GPS Navigators – this is a necessary and useful thing in everyday life, with which you can go on a trip and not be afraid to get lost!
