Difference Between GPS and Glonass

18 February 2023



GPS (Global Positioning System) and GLONASS (Global Navigation Satellite System) are two different satellite-based navigation systems that are used to determine the location of an object on Earth. Both GPS and GLONASS can provide users with information about their location, speed, and direction of movement.

Here are some key differences between GPS and GLONASS:

1. Origin: GPS was developed and is maintained by the United States government, while GLONASS is a Russian system.

2. Number of Satellites: GPS currently has 31 operational satellites in orbit, while GLONASS has 24 operational satellites.

3. Coverage: GPS has global coverage, while GLONASS provides better coverage in the northern hemisphere, particularly at high latitudes.

4. Accuracy: Both systems provide similar levels of accuracy, but GPS has a slight advantage in terms of precision.

5. Availability: GPS is more widely used and is available in many more devices, including smartphones, while GLONASS is less commonly used.


In recent years, many GPS devices have begun to support both GPS and GLONASS, which can improve their overall accuracy and provide better coverage in areas where one system may be weaker. It is important to choose a device that supports both systems if you are looking for the most accurate and reliable navigation information.
