Navigation, Signal Analysis and Simulation group
The NavSAS Research Group
2
Starting from a signal processing approach to Navigation and Positioning
the group evolved to cover several aspects of the positioning chain, by
using a theoretical and simulation approach complemented with
experimental skills.
NavSAS, according to a EC survey is considered one of the 3 teams “of
excellence” in the field of Navigation in Europe
NavSAS research group is a joint team of
Politecnico di Torino and ISMB
Research in the areas of satellite navigation
and Positioning
Joint labs in the Navigation Technologies
research area of ISMB

• N-Gene is a real time software receiverfor GPS L1 and Galileo E1 signals
• N-Gene has been developed by the NavSAS group, thanks to the experience gained over the past years on GNSS technologies
• Powerful research tool, often used in projects and internal scientific programs
• Useful as data recorder, storing raw data samples to hard disk and for post-mission analysis
• Enables processing of simulated data compliant to both GPS and Galileo
N-Gene software receiver

Higher education
11
The Higher Education Unit cooperates with many European and Asian Universities inthe field of the Higher GNSS Education.
In Asia the focus is on ASEAN countries, in particularVietnam and Thailand. The NAVIS Centre in the HanoiUniversity of Science and Technology (Vietnam),opened in 2010 and it is dedicated to European GNSSTechnology .
In Europe the main initiative is G-TRAIN. Aim of thisproject is to set up a European framework for highereducation in the field of GNSS boosting networkingactivities among academia.
