GPS is an abbreviation for the English Global Positioning System, translated as a global positioning system. The GPS system includes 24 space satellites and millions of stations on the Earth's surface. The principle of the system is that the receiver receives a signal from the satellite and determines its position. The device displays the geographic coordinates of its location on an electronic map.
Types of GPS navigators
A car navigator is a small electronic device with a display and a processor. Car navigators are divided into two types of installation. This is a stationary car navigator, which is installed in a specially provided place, and a mobile navigator, which is attached to the windshield of a car. Navigators differ in the installed software and maps. The most famous navigation software: Garmin, Navitel Navigator, Avtosputnik.
Maps for navigators
When buying a navigator, the most important determining criterion is the map. You need to know in advance which maps of which region are needed, whether these maps are installed on the device and whether it is possible to download them additionally.
All types of maps supplied with the navigator must be able to automatically plan a route (support routing), have a high level of detail, voice guidance and three-dimensional image.
The most extensive road map atlases are available on Garmin instruments. Garmin quite often makes updates to navigation atlases for the Russian Federation, achieving a high level of detail. The advantage of Garmin maps is extended coverage, technical support and ease of use. The only drawback is that the official additional cards will have to be purchased for a fee.
Detailed terrain maps are also developed for Navitel devices. Map updates are released several times a month. There are detailed detailed maps of more than 2000 cities in Russia. These maps are not available for free, the purchase of cartography is required.
Address search is very conveniently implemented in the maps of the Avtosputnik navigation system. The keyword searches for all matching combinations. In order to determine whether the cards are suitable or not, the manufacturer suggests using a 30-day trial version.
Despite the constant expansion of coverage areas with maps of Russia, many areas are still not displayed on the official maps of manufacturing firms. Here resources can help, from which you can download and install a map of the region of interest for free and install on your device. The most famous resource is openstreetmap.ru/navigator. The basis for all navigation maps is the open-source mapping project OpenStreetMap. On this resource, the map is created by the users themselves. You just need to select the appropriate map format, download and install on the navigation device.
