The system is almost as accurate as GPS and is accessible to any user equipped with wireless access points. Some companies that use Glonass chips in their equipment are Apple, Garmin, Sony and HTC.
In addition to its satellite network, Glonass uses terrestrial networks, located mainly in Russia, Antarctica, Brazil and Cuba, forming a kind of triangle, according to an article by BBC Mundo.
What is it for?
High precision services are oriented for uses in personal navigation, search and rescue, geodesy and cartography, construction, land transportation, agricultural industry, aviation, space, maritime transportation, environment, as well as communications and synchronization.
As of 2012, the GLONASS system has been moving in the direction of efficiently solving positioning, navigation and timing tasks for the benefit of the defense, security and social and economic development of the country in the near and distant future, indicates the system website.
Where does the Russian GPS operate?
Like GPS, the GLONASS satellite network offers worldwide coverage, with similar accuracy to GPS, although in some parts of the world such as the southern hemisphere, the accuracy of the US system may be slightly better.
