PreNav, Inc. engages in developing automated systems for infrastructure inspection. The company’s system consists of a commercial drone, a guidance robot on the ground, and software to plan the mission and analyze the data. Its technology allows drones to navigate around cell towers, wind turbines, bridges, buildings, and other complex structures at centimeter-or-better precision; inspect nuts, bolts, serial numbers, cabling, and damaged areas, as well as take measurements of key components; and take photographs from precise locations in close proximity to structures to build accurate 3D reconstructions of industrial assets. PreNav, Inc. was founded in 2013 and is based in San Carlos, California.
