List of Global Navigation Satellite Systems currently operational and in development
Satellite navigation system performance is based on the following :
1 – GPS of the United States of America
2 – GLONASS of Russia
3 – Galileo of the European Union
4 – BeiDou of People’s Republic of China
5 – IRNSS or NAVIC of India
6 – QZSS of Japan

Content: It makes use of radio navigation satellites and is also utilized by the Aerospace Defence of the Russian Forces. It consists of 24 full orbital constellations of satellites that allow for global coverage. 3 – Galileo of the European Union
Galileo is the European Union satellite navigation system introduced in 2002. The European Space Agency also makes use of this system and is used as an alternative to the United States GPS. It makes use of 30 satellites that are in medium Earth orbit. It has been designed to be compatible with the GPS system of US and receivers can make use of combined signals from GPS and Galileo, mainly to increase the level of accuracy. 4 – BeiDou of People’s Republic of China
China has been using the system BeiDou for its military and civilian navigation purposes. It is currently in the second generation and was formerly known as COMPASS, and serves the Asia-Pacific region in addition to China. It makes use of 30 Medium Earth Orbit Satellites and 5 satellites that are in geostationary orbit. 5 – IRNSS or NAVIC of India
IRNSS (Indian Regional Navigation Satellite System) or NAVIC (Navigation with Indian Constellation) is the satellite navigation system used by the Indian Space Research Organization, which is directly controlled by the Indian Government.
