Unearthing the Future of Autonomy

GPR’s Ground Positioning Radar™, like traditional sensors, uses landmarks to position autonomous vehicles relative to road features that matter. The key difference is that GPR landmarks are deep beneath the driving surface. This character-rich data, which is extremely unique even in seemingly homogeneous environments, is the key to reliable and accurate localization across terrains.

Since GPR data is protected by the ground it is always available, consistently detectable, and rarely changes for the most robust vehicle positioning.

The Missing Modality

Autonomy should not be confined to pristine conditions and crystal clear lane markings—and with GPR, it isn’t.

Independently, or in combination with other sensors, GPR provides mission-critical localization for everything that moves autonomously, down to the centimeter.

Seeing When Other Sensors Can't

Even the most advanced sensors fail to provide a reliable position in many common scenarios. Other solutions monitor and track conditions in front of and surrounding a vehicle, relying on an uninterrupted line of sight to detect relevant landmarks.

The line of sight can be easily obstructed by surrounding objects or harsh conditions like snow, heavy rain, and fog. In addition, the surface landmarks traditional localization systems rely on can be homogeneous, scarce, or frequently changing, making them unreliable and poorly suited for localization.

The Surface Changes. GPR Maps Don’t.

By comparison, the subsurface is exceptionally stable, character-rich, and accessible.

GPR scans the unchanging subsurface below the vehicle to place it precisely on the roadway. Our technology is unaffected by GPS availability, terrain, and other common sensor fail points. Mapping is easily achieved via crowdsourcing or mapping fleets. Any vehicle with GPR for localization can expand, update, or validate the GPR map layer.
