SMF demonstration

Submitter: SMF team
Description: The development of the Signal-in-Space Monitoring Facility (SMF) for Galileo is formally finished on April 6 with the demonstration to Thales-Alenia-Space in Italy (TAS-I) and the European Space Agency (ESA).

This monitoring facility is part of the In-Orbit Validation of the first four Galileo satellites. Its prime task is to receive the satellite signals as accurate as possible, perform various signal analyses and transfer the data to TAS-I. At TAS-I, the data will be combined with the outcome from other facilities.

The demonstration started in the morning by capturing signals from Giove-B, which is a Galileo test satellite. After the satellite disappeared behind the horizon, calibration measurements were performed to determine accurately the system signal gain and system phase behavior as function of the frequency. Finally the measurement data was corrected with the calibration data and the signal analysis took place. All went flawlessly.

During the automated measurement procedures, various presentations were given from TAS-I, ASTRON and S&T. When the final measurement results were presented by S&T, the press was invited to share with us this special moment.
