Satellite navigation is what?

Satellite navigation is primarily a high-precision tool for determining the coordinates of the location of physical objects. Find the desired objects with the help of modern navigation systems can be practically anywhere in the world. Actively developing modern satellite systems are able to provide an extensive coverage for the transmission of accurate navigation data.

What is satellite navigation?

Satellite navigation systems are a wide range of electronic equipment and hardware in the form of a set of space and ground equipment.

Navigation - a tool for determining the coordinates of the geographical location of objects. However, the most modern means of satellite navigation make it possible to determine infallibly parameters such as the speed or direction of movement of an object and so on.

The navigation systems are based on orbital satellite constellations, which can contain from two to several dozens of satellites. Their main task is the exchange of radio signals between themselves and the ground control systems. In turn, the client equipment of users is used to determine the required coordinates based on the information received from the navigation control centers.

Principle of operation of the satellite navigation system

The work of satellite systems is based on determining the distance from the satellite to the antenna of the object, the coordinates of which must be calculated. A conditional map of the location of all satellites in the system is known as almanac. Most satellite navigation receivers are able to store such a card in memory and instantly receive the necessary data. Thus, navigation programs based on geometric coordinate structures allow you to calculate the exact position of the object on the map.

Personal satellite navigators

Modern personal navigators are high-tech devices designed not only to receive satellite navigation data, but also to provide the user with rich multimedia capabilities.

In combination with the subscriber equipment with the availability of specialized software, personal navigators provide opportunities for monitoring both stationary objects and transport.

If we talk about the drivers of vehicles, then for them navigation is, first of all, the possibility of obtaining detailed recommendations regarding the selection of the most successful routes, the follow-up of which allows to optimize fuel consumption and significantly reduce travel time.

Prospects for the development of satellite navigation systems

Currently, satellite navigation is a system that is globally applied for cartographic purposes. The bulk of navigational data received by GPS is now controlled by the US military department. Therefore, from year to year, an ever more pressing issue for the world community is the deployment of alternative systems, where the most promising are the European project "Galileo" and the Russian "Glonass".

Based on the opinion of marketers, it can be argued that the coming decades promise the market of navigation services a significant development. Similar views are also held by developers of projects in the field of satellite navigation. This is confirmed by the data of numerous research centers that note the growing demand for navigation services among owners of portable digital devices.
