The SIGnal processing and NAVigation (SIGNAV) is a research group of the TELECOM lab. It focuses on navigation and positioning topics in which Global Navigation Satellite Systems (GNSSs) play a key role.

Targeted applications

GNSS for Civil Aviation 

The SIGNAV research group has a worldwide recognized technical and operational expertise in all fields and systems (current and under development) related to the use of GNSS by civil aviation: SBAS, GBAS, ABAS (RAIM, AAIM, ARAIM). SIGNAV is also involved in research areas related to ground navigation on an airport platform.

Land Navigation

The SIGNAV research group has developed a strong expertise regarding land applications requiring a navigation platform with a high quality of service for safety, liability or financial reasons. The SIGNAV research group is also strongly involved in the development of low-cost precise positioning platforms for urban environments. 


Scientific fields of expertise of the SIGNAV team

1 - Integrity Monitoring

Knowledge of current and future civil aviation navigation systems, Participation to civil aviation experts' group and standardization bodies, Development of integrity monitoring adapted to urban environments and hybridized navigation solutions

2 - GNSS Receiver Signal Processing

Acquisition, Tracking, Demodulation, Advanced processing of modernized GNSS signals, Robust tracking in difficult environments, Signal quality indicators to assess the quality of GNSS measurements in all environments, Mitigation of multipath and interference

3 - Multi-sensor Navigation

Hybridization of two or more of the following sources of information for navigation: GNSS, inertial sensors, magnetometers, cameras, odometers, barometers, maps

4 - GNSS Signal Design

Definition of new modulations, Navigation message design and advanced encoding schemes, Assessment of the suitability of new signals for specific applications 

5 - Precise Positioning

RTK and PPP adapted to urban environments

The research group members also are also actively contributing to GNSS, navigation and signal processing education through initial (bachelor and Master students) and professional training.
