How Ground Positioning RadarTM Works

GPR's WaveSense Maps Unique and Consistent Data

Ground Positioning Radar (GPR) harnesses the unique and consistent characteristics of subsurface features to create highly accurate positioning data for autonomous vehicles. By utilizing low-frequency radar pulses that penetrate 2-3 meters into the ground, GPR generates a detailed map of the subsurface environment. This innovative approach offers several key advantages:

> Stability over time

> Infrastructure-free solution

> All-weather performance

> Available day and night

> Independent of GPS

Subsurface data is highly rich, easy to localize against, and stable over time

The Key to Robust Positioning

Centimeter level precision with GPR ground penetrating radar

Map

Specialized radar equipment mounted on vehicles collects detailed subsurface scans during initial mapping drive. Advanced algorithms process the raw radar data, identifying unique subsurface features and patterns to create 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 without relying on lane markings or an unpredictable surface environment.

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.
