What is a satellite navigation system and how does it work?
More details on frequency and antenna applications can be found here.
Why are there different satellite navigation systems?
Did you know that “GPS” is NOT an umbrella term for satellite navigation systems?
Global Navigation Satellite Systems
Global Positioning System (GPS)
Global Satellite Navigation System (GLONASS)
Galileo
BeiDou Navigation Satellite System (BDS)
Quasi-Zenith Satellite System (QZSS)
Indian Regional Navigational Satellite System (IRNSS)
In Conclusion

Content: This sat nav system is the only other navigational system in operation with global coverage and of comparable precision. Galileo
Galileo is a global navigation system developed by the European Union and European Space Agency intended primarily for civilian use. Named after the Italian astronomer Galileo Galilei, one of the goals was to provide a high-precision positioning system for European nations that would be independent from the Russian GLONASS, U.S. GPS, Indian IRNSS and Chinese Compass systems. The 30-satellite system first launched in 2011 with expected completion at the end of 2020. The use of the basic services is free and open to everyone, while the high-precision capabilities will be available for paying commercial users and for military use. BeiDou Navigation Satellite System (BDS)
The BeiDou Navigation Satellite System (BDS) is a Chinese satellite navigation system, consisting of two separate satellite constellations. The first, BeiDou-1, was launched in 2000 and decommissioned in 2012, offered limited coverage and navigation services, mainly for users in China and neighboring regions. The second system, or BeiDou-2, was launched in 2011 with a partial constellation of 10 satellites in orbit and serves customers in the Asia-Pacific region. China’s third generation system, or BeiDou-3, was launched in 2015. Quasi-Zenith Satellite System (QZSS)
The Quasi-Zenith Satellite System (QZSS) is a four-satellite regional time transfer system and Satellite Based Augmentation System for the Global Positioning System developed by Japan, serving the Asia-Oceanic region.
