Activities mainly carried out in the frame of the CCTF subWG on Algorithms and in the projects related to 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
