Design a robust positioning system that combines collaboration and hybridization

FROM SPACE

CNES has developed a range of patented technologies (EP3249429 ; EP3316001) that would enable an autonomous vehicle to calculate its spatial position with greater accuracy and robustness in complex or degraded environments: Dynamic optimization of the orientation of the vehicle’s GNSS antenna to limit interference (bounce, etc.) and improve the signal; collaborative positioning by exchanges of GNSS data and relative positioning (LIDAR) between vehicles; positioning inside buildings (garages, basements, etc.) by GNSS signals modulated for use via Li-Fi (or VLC – Visible Light Communication); multipath calculation (bouncing of the GNSS signal distorting the calculation of positioning) by collaborative calculation of differential positioning between two antennas.

TO THE CHALLENGE

Imagine the autonomous car of the future, which combines certain technologies (GNSS, LIDAR, etc.) and information flows (locating other vehicles, etc.), so as to be able to estimate its spatial position with great accuracy, under absolutely any circumstances (in an urban area surrounded by large buildings, in a tunnel, etc.).

Explain the limitations of each technology according to the environment in which the vehicle operates and come up with a hybrid, collaborative and innovative system to address these issues. Identify the different information flows and modes of communication required by the system, and their corresponding value chain.

Imagine a business model that would distribute the added value among the various participants. Create a context for the imagined system by sketching the synopsis of a journey and indicating for each situation how your system addresses the need for robustness and precise positioning.
