Satellite navigation is primarily a high-precision means for determining the coordinates of the location of physical objects. You can find the desired objects with the help of modern navigation systems almost anywhere in the world. Actively developing modern satellite systems are able to provide extensive coverage for the transmission of accurate navigation data.
What is satellite navigation?
Satellite navigation systems are a wide range of electronic equipment and technical means in the form of a combination of space and ground equipment.
Navigation is a tool for determining the coordinates of the geographical location of objects. However, the most modern means of satellite navigation make it possible to almost accurately determine such parameters as the speed or direction of an object, and so on.
Navigation systems are based on orbital satellite constellations, which can include from two to several dozen satellites. Their main task is to exchange radio signals between themselves and ground control systems. In turn, the user's client equipment is used to determine the desired coordinates based on the information received from the navigation control centers.
The principle of the satellite navigation system
The operation of satellite systems is based on determining the distance from the satellite to the antenna of the object whose coordinates must be calculated. A conditional map of the location of all satellites in the system is known as an almanac. Most satellite navigation receivers are able to store such a map in memory and instantly receive the necessary data. Thus, navigation programs based on the geometric constructions of coordinates 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 a rich multimedia experience.
In combination with subscriber equipment with specialized software, personal navigators provide the ability to monitor both stationary objects and vehicles.
If we talk about drivers of vehicles, then for them navigation is, first of all, an opportunity to receive detailed recommendations regarding the choice of the most successful routes, following whichallows you to optimize fuel consumption and significantly reduce travel time.
Prospects for the development of satellite navigation systems
Today, satellite navigation is a system that is used globally for mapping purposes. The bulk of GPS navigation data is now controlled by the US military. Therefore, from year to year, the deployment of alternative systems, where the European Galileo project and the Russian Glonass look like the most promising, is becoming an increasingly urgent issue for the world community.
Based on the opinion of marketers, it can be argued that the coming decades promise significant development for the navigation services market. Similar views are also held by the developers of projects in the field of satellite navigation. This is confirmed by the data of numerous research centers, which note an increase in demand for navigation services among owners of portable digital devices.
