Research Units

NAvSAS is focused on design and development of new technologies and systems related to Global Navigation Satellite Systems (GNSS). Researchers’ activity ranges from the study of algorithms and software radio solutions for GNSS receivers to the development of GNSS applications for both mass-market and professional users. The team has strong international links, in particular, at extra-European level, with South-East Asian countries. The NavSAS group is organized in three main units:

  1. GNSS Core Algorithms: Analysis of new algorithms for multi-system receivers and development of real time GNSS receivers in sw radio technology;
  2. GNSS Platforms for Safety and Environment: Design and development of embedded platforms, enabling new GNSS-based services;
  3. International Cooperation on GNSS: Design and development of research and higher educational activities with extra-EU institutions, with particular focus on South East Asian countries.


NavSAS research activity addresses many topics related to GNSS, navigation and signal analysis. In particular:

  • High-Sensitivity receivers, Assisted GNSS;
  • Interference monitoring, Detection, Mitigation;
  • Localization with signals of opportunity and hybrid systems;
  • Multipath modeling;
  • P2P localization;
  • Satellite Navigation Software Receivers;
  • Spoofing and jamming detection and mitigation;
  • Scatterometry;
  • Ionospheric scintillation.
