The aim of these activities is to improve the performance of positioning and navigation systems in urban canyons, which represent an adverse environment for GNSS signals (poor GDOP, low C/No ratio, interference).
One of the research topics concerns mitigation techniques, using precorrelation processing inside the receiver or adaptive antenna arrays.
Another topic aims at defining a new approach for GPS/INS integration. These architectures based on low cost sensors (odometer, inertial sensors, image sensors) benefit from the laboratory’s experience in the development of complex systems.
This activity involves the following fields:
- antenna processing for GNSS signals (supported by the adaptive antenna group),
- secure navigation in urban environments,
- non linear filtering technique for low cost navigation systems,
- GNSS/MEMS inertial sensors integration,
- reconfigurable in-space receivers for GNSS and TM/TC signals,
- new air interfaces for navigation systems in S & C frequency bands.
