GIOVE and Galileo

ILRS Mission Support Status:
The ILRS Governing Board has approved the Galileo mission support request. Satellite laser ranging data are mainly needed for the validation of the microwave orbit determined from a global tracking network.
The first Galileo in-orbit validation element, GIOVE-A was launched on 28 December 2005. The first orbit and clock characterization campaign started on 22 May 2006 and lasted for eight weeks. For this first campaign, the Galileo project had two GPS+GIOVE sensor stations, one at ESTEC (The Netherlands) and one in Torino (Italy). With such a configuration, the project can only perform a coarse characterization of the on-board clock, because of the limited number stations and because both stations are in Europe. SLR tracking data are essential for "fixing" the orbit so that the clocks can be well synchronized. Additional tracking campaigns will follow. In the interim, the GIOVE tracking priority is comparable to GPS and GLONASS.
