The Time and Frequency Dept participates to the development of the Galileo System in collaboration with European space industries and the European Space Agency.

In early 2006, an experimental phase called "Galileo System Test Bed V2 (GSTBV2)" has been launched and INRIM takes part to it hosting a Galileo prototype receiver, generating the "reference signals" for the Test Bed experiments, and analyzing the data coming from the first experimental Galileo satellite, in order to characterize its on board clock. In the following figures, the Galileo prototype receiver and a scheme if the installation at INRIM is shown.

INRIM is also involved in two additional projects:

- Galileo development (phase CDE1) supported by ESA, INRIM contributes to the development of the Galileo time laboratory named Precise Time Facility by designing the time scale algorithm.

- Galileo Time Service Provider (TSP) Prototype, supported by the European Union, INRIM contributes as UTC(k) laboratory providing clock and comparison measures, and taking care of the relationship of the TSP with the BIPM and the main Standardization organizations.

Activities mainly carried out in the frame of the new European Satellite Navigation System Galileo (www.esa.int/esaNA/) in which INRIM collaborates on clock error modelling and time scale generation.

The main research activities are currently devoted to:
- Clock error modelling and uncertainty evaluations
- Optimal and robust time scale algorithms
- Characterisation of time-varying clock noise with the Dynamic Allan Variance
