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
