GLONASS
Sign in to saveThe Global Navigation Satellite System (), usually referred to by the acronym GLONASS (, ), is a Russian satellite navigation system operating as part of a radionavigation-satellite service. It provides an alternative to the Global Positioning System (GPS) and was the second navigational system in operation with global coverage and of comparable precision.
GLONASS is a Russian satellite navigation system that works similarly to GPS, allowing people and devices to determine their precise location anywhere on Earth. It was historically significant as the second global navigation system to achieve worldwide coverage with accuracy comparable to GPS, offering an independent alternative to the American system.

The Global Navigation Satellite System (), usually referred to by the acronym GLONASS (, ), is a Russian satellite navigation system operating as part of a radionavigation-satellite service. It provides an alternative to the Global Positioning System (GPS) and was the second navigational system in operation with global coverage and of comparable precision.
Satellite navigation devices supporting both GPS and GLONASS have more satellites available, meaning positions can be fixed more quickly and accurately, especially in built-up areas where buildings may obscure the view to some satellites. Owing to its higher orbital inclination, GLONASS supplementation of GPS systems also improves positioning in high latitudes (near the poles).
