How Ground Positioning RadarTM Works

A Wealth of Unique and Consistent Data Lies Beneath the Surface

Subsurface features, such as the geological composition of soil and rock layers, remain relatively stable over time. Additionally, the subsurface environment hosts hidden infrastructure like utility lines, drainage systems, and underground cables.

This stability translates into a reliable source of information for autonomous vehicle localization. No infrastructure required, natural ground makeup provides more than enough unique character for accurate positioning.

The Key to Robust Positioning

Map

Integrated underneath the vehicle, GPR sends low frequency RADAR pulses 2-3 meters into the ground to collect radar data from below the road, creating a detailed map that remains stable over time.

Localize

Real-time radar data is then matched to the previously created GPR map layers. Through this automated process, GPR positions the vehicle based exclusively on underground data.

Integrate

GPR feeds the resulting position directly into the vehicle’s navigation system. This positioning provides reliable and accurate driver assist and autonomy features like lane-keeping, automated parking, and highly automated systems including L4 autonomy.

The GPR system seamlessly integrates with existing localization inputs and fusion systems.

Compatible Across Industries

Ground Positioning Radar™ provides automakers, Tier 1 suppliers, and autonomy providers with the localization performance and development tools to deliver new levels of safety and performance for their customers.

The character rich subterranean maps developed by GPR systems are being leveraged across commercial industries including commercial robots, mining automation, passenger shuttles, and seaports, and more.
