About
Ground-penetrating radar helps locate buried utilities and assess concrete, but conventional surveys require manually marked grids and positioning systems that work poorly in basements, tunnels and other locations without satellite signals. SubterraNav combines a mobile robot, ground-penetrating radar, 3D laser scanning and motion sensors to map surface and subsurface conditions while tracking its own position. Automated processing removes invalid movements and converts usable scan paths into accurately located radar profiles. Centimetre-level testing suggests the system could make infrastructure inspection faster, safer and more consistent.
