Satellite navigation is playing a growing role within all areas of today's mobile society. Navigation receivers are made for aircraft, ships, ground vehicles, and for hand carrying by individuals.
This report describes briefly the US American GPS and the Russian GLONASS system which were designed and controlled by and for the military. An outlook is given on the future European GALILEO system which is designed for civil applications as well as on the three independent satellite based augmentation systems which will fulfil the requirements for high quality positioning information for aviation.
