Guardian RF

Guardian RF builds low-cost, passive radiofrequency sensors that make low-altitude airspace observable in real time. Founded in 2024 by three Georgetown physics majors, the company deploys palm-sized 'Scout' sensors that detect the control signals drones and their operators emit, triangulating both across a mesh network. Its systems have been battle-tested on the front lines in Ukraine and are now fielded at Vandenberg Space Force Base and across U.S. airports and event venues, turning drone detections into structured, shareable intelligence.
