Car satellite navigators include specialized GPS navigators, navigation devices, both stationary and semi-stationary. The most adapted to installation and use in the car. Of course, many of the portable GPS navigators, with some limitations in functionality, can also be used on the car..
GPS satellite navigators in the car, purpose and scope.
Car GPS satellite navigators are designed to make traveling by car as convenient, comfortable and safe as possible. And all this with minimal time and fuel. In relation to car GPS navigators, the concept of navigation is used in a purely everyday sense, meaning navigational support for a trip along a laid route. Allowing the driver or navigator to constantly monitor the vehicle’s location on an electronic map and to receive timely messages and recommendations about upcoming turns and maneuvers.
The ability to orient drivers, though generally very individual, is very limited, and even in familiar metropolitan cities or in a dense network of roads, it sometimes creates difficult, well-known problems. What can we say about the movement in an unfamiliar area. Probably, any car enthusiast can remember more than one case when he got lost in an unfamiliar place.
The emergence and development of the use of automotive GPS-navigators contributed to several of the following reasons. The frequency of long trips has increased significantly. In a developed road network, route selection has become a complex, ambiguous and multi-criteria task. Remembering the long route has far exceeded the capabilities of the human driver. Increased traffic intensity and speed have led to a decrease in travel safety. Especially in bad weather and in unfamiliar areas.
Modern road junctions made at the level of engineering, for high-speed maneuvering require a detailed preliminary study. Indicative in this regard, the current situation in Japan, a country that is a leader in the use of car GPS-navigators. One of the reasons for the rapid development of car navigation systems in Japan and the state’s attention to this industry is that traffic problems in this country cannot be solved only by improving roads and increasing their number. Since the land here is very expensive, and construction takes considerable time.
According to the Japanese, the optimization of the route of each car will help to reduce driver fatigue and ultimately reduce the number of accidents and traffic accidents. An additional benefit may be more efficient use of fuel, which is also a sore point in Japan’s resource poor, and improved environmental situation..
The first car GPS navigators appeared in the early eighties, but their intensive use began only in the mid-nineties, when the problems of storing electronic maps in memory were solved and the methods of speech synthesis were mastered, thanks to which the system acquired the ability to deliver voice messages. This innovation made it possible for the driver not to take his eyes off the road and concentrate fully on driving.
Also in the West, the problems of providing systems with electronic cards and their timely operational correction were completely resolved. If in Japan about half a million automobile GPS-navigators were installed annually, in the USA their distribution proceeded at a slower pace. This is explained by the fact that in America there are a lot of good roads and a relatively low density of cars; traffic and weather conditions affect the speed and safety of movement almost exclusively.
Therefore, a surge in interest in car navigation systems in America was outlined only in mid-1999. When it became possible to receive traffic and weather maps for any region of the USA in real time for route planning. By design, car GPS navigators can be divided into systems that are embedded in the panel (dashboard), and systems that represent a separate independent design that can be installed directly on the panel or mounted on the windshield. The main manufacturers of embedded navigation systems are companies traditionally engaged in automotive audio: Bosch, Philips, Blaupunkt, Alpine and Pioneer.
Who and how heavily uses car GPS.
The data of the large car navigation market in the West show that almost 36% of cars with navigation are in the class of SUVs, and 25% are in luxury cars. Professional users of car GPS navigators are freight forwarders, sales representatives, real estate managers, and even couriers. For these categories, the main quality of the system is the ability to automatically create a route and help in following it.
It was found that thanks to car navigators, about 50% of the time is saved when traveling from point A to point B, especially if A and B are in different countries. Non-professional users turn to car GPS-navigators in order to obtain information about places of entertainment and recreation. An important aspect for them is a large database of so-called points of interest. Restaurants, hotels, gas stations, monuments and much more. This category also includes tourists traveling by car..
