How Ground Positioning RadarTM Works

GPR's WaveSense Maps Unique and Consistent Data

Subsurface features remain relatively stable over time. 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.

GPR uses this data to generate high definition maps. When a vehicle is in motion, GPR tracks and matches a real-time radar scan with the subsurface map. This enables precise positioning regardless of poor weather or visibility, faint road markings, or other common challenges facing autonomous mobility.

The Key to Robust Positioning


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.


Real-time radar data is then matched to the previously created GPR map layers. Through this automated process, GPR positions the vehicle without relying on lane markings or an unpredictable surface environment.


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.

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, seaports, and more.
