Galileo is a European initiative for the development of a civil and global infrastructure for positioning and navigation with satellites. The system now is in the stage of development and it is to be expected in operation in 2008. Galileo will consist of about thirty satellites in medium high orbits around the earth. The final object of Galileo is European sovereignty in the rapid expanding markets for applications of positioning, navigation and transfer of time. It is expected that the macro economic benefit of Galileo through the sale of equipment, supplies and services will be one magnitude bigger than the investments for putting up the infrastructure in space and on earth.

Decisions on the various components of the system like the structure of the signal, the frequencies and the geometry of the configuration of the satellites have been made during the definition phase of the system. After this phase models will be developed and calculations will be made for applications of precision positioning and navigation with Galileo.

The Ph.D. research project 'Positioning with the European Galileo system' has started on March 1 2003 at Delft University of Technology. The researcher is Mr. A. Quan Le and his supervisor is Dr.Ir. C.C.J.M. Tiberius (TU Delft, DEOS). The project is supported financially by the NCG, TU Delft and the Survey Department of Rijkswaterstaat. The main research subjects are the performance of Galileo on positioning and navigation, transfer of time and atmospheric research. Likewise the integration with the modernized American positioning and navigation system GPS (Global Positioning System) will be researched concerning the effect on the performances of Real-Time Kinematic positioning and the relation with the Dutch AGRS.NL (Active GPS Reference System for the Netherlands). The central question is what Galileo is able to offer in addition to the existing GPS and which possibilities this offers, also for the Dutch professional practice and the Dutch trade and industry.
