This colloquium intends to bring together leading members of the European scientific community and their international partners. One of its aims is to propose to Galileo partners means of enhancing the scientific use of Galileo and to contribute to GNSS development based on scientific approaches.

The purpose of this colloquium is to review the various possibilities to use navigation satellites such as Galileo for scientific purposes, and to investigate how these scientific requirements can contribute to make the most of the present systems, and define their future evolutions. The conference will be organized as a series of plenary talks and two parallel half day sessions.

The conference is organised by ESA, the University of Padova and COSPAR. The meeting is supported by the Académie de l'Air et de l'Espace, Bureau des Longitudes, IAG, IGS, URSI and ASI. Companies and organisations interested in becoming Sponsors, please contact: Prof. Cesare Barbieri, e-mail:
