Navigation, Signal Analysis and Navigation, Signal Analysis and Simulation Group 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

GNSS core algorithms

8

• Interference and spoofing detection, algorithms design and signal quality monitoring

• EGNOS-enabled receivers and high accuracy differential systems

• Assisted-GPS, hybridization with communication networks and cooperative

positioning concepts

• GNSS receivers core technologies for mass-market and Public Regulated applications

• Multi-systems and multi-frequency

receivers

• SW Radio implementations

• 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

GNSS platforms for safety and environment

10

• Test of new prototypes and on field measurements

• Remote sensing measuring GPS back-scattered signals with software receivers

• Design of efficient systems, based on GNSS technologies, for fleet management

• Core technologies of Safety-of-Life (SoL)receivers and applications

• Secure navigation and analysis of newliability-critical systems based on GNSS

• Countermeasures to civilian spoofing andauthentication mechanism

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.
