Within the past 20 years satellite navigation systems have been utilized for a variety of applications. They are used for the determination of position, velocity and time. Presently two military owned satellite navigation systems called GPS (by the USA) and GLONASS (by Russia) are operable and can be used by civilian users. Both systems are not designed to fulfil requirements of special civilian user groups, for example the geoinformation (GIS) sector. Neither continuous availability nor reliability are guaranteed with the existing systems.
The new civilian European navigation system GALILEO, presently under development for full deployment until 2010, is designed to satisfy the needs of the growing variety of applications, where satellite navigation is used. The combined use of all three systems (GALILEO+GPS+GLONASS) will have a huge impact and improvement on signal availability, reliability and integrity, especially in urban environments.
This paper gives an overview of the development status of the European satellite system GALILEO. A description of the system design and signal structure is given. Special attention is given to the diverse services, especially for the use in geographic information systems (GIS). Some applications, for example the use of GALILEO in pipeline documentation, are discussed in more detail.
