What are the differences between GPS and GLONASS?

With GPS, satellites use the same radio frequencies but have different codes for communication, while GLONASS satellites have the same codes but use different frequencies, allowing satellites on the same orbital plane to communicate with one another.

What is the difference between GPS and GPS Glonass?

The Difference Between GLONASS and GPS GNSS

For starters, the US GPS network includes 31 satellites, while GLONASS uses 24 satellites. The 2 systems also differ somewhat on accuracy. GLONASS position accuracy is 5-10m while GPS is 3.5-7.8m. Therefore, GPS outweighs GLONASS in accuracy as lower error numbers are better.

What's the difference between GPS Glonass and GPS Galileo?

GLONASS is usually more accurate in mountainous areas, while Galileo is more accurate in urban areas. Galileo should be slightly more accurate than GLONASS, depending on its surroundings. GLONNAS is Russian satellite navigation system and Galileo is European.

What is the advantage of GLONASS over GPS?

The full orbital constellation consists of 24 satellites into three orbit planes. The orbit altitude is ~19,100 km above the Earth's surface. A significant advantage of the GLONASS, as compared to the GPS, is that the GLONASS has an orbit inclination of ~65°, that is ten degree higher than the GPS orbit inclination.

How is Galileo different from GPS?

The Galileo system has a greater accuracy than GPS, having an accuracy of less than 1 m when using broadcast ephemeris (GPS: 3 m) and a signal-in-space ranging error (SISRE) of 1.6 cm (GPS: 2.3 cm, GLONASS and BeiDou: 4–6 cm) when using real-time corrections for satellite orbits and clocks.
