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.
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.
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
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
