WaveSense has raised $15 million. This round was led by top technology investors Rhapsody Venture Partners and Impossible Ventures.

Through a proprietary ultra-wide band radar, WaveSense creates a map of subsurface signatures from which self-driving and other ADAS-enabled vehicles can navigate. Through unique design in hardware, software, and systems, WaveSense’s GPR technology allows vehicles to localize and determine their precise location where current AV technologies, including lidar and camera-based systems, fall flat—especially when lane markings are poor, in adverse weather and terrain conditions, and in areas with poor GPS availability.

WaveSense plans to advance the integration of their centimeter-level precision technology into consumer vehicles in collaboration with some of the world’s largest automakers and suppliers. The company recently demonstrated centimeter level localization accuracy and reliability on roads without lane markings, during a snowstorm, in a parking garage, and on unpaved terrain.
