The Growth and Expansion of Precise Navigation and Timing

  • Joseph N. Pelton
Part of the Springer Praxis Books book series (PRAXIS)


There are actually many terms that are used to characterize Global Navigation Satellite Services (GNSS) around the world. Some of these terms include: Precision Navigation and Timing (PNT), Sat Nav, and GPS (for Global Positioning Satellites). There are also a growing number of systems that provide this type of service. These include the Glosnass system operated by Russia, the Chinese Beidou and Compass systems, the Japanese Quasi-Zenith system, the Indian Regional Navigation Satellite system, and the European Galileo system. There are possibly others that might be initiated in the future, such as system deployed by the Republic of Korea and one operated by the United Kingdom if it is not able to negotiate continued participation in the Galileo system due to Brexit [1].
