# 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.

- **Founded:** 2024
- **Headquarters:** Washington, District of Columbia, United States
- **Founders:** Lucas Raskin (CEO), Eli Kerstein (CTO), John Andrzejewski (COO)
- **Team size:** 13-15 employees
- **Products:** Scout, Mosaic, Intelligence Platform
- **Notable:** Finalist at Falcon Peak 25.2, a DoD counter-UAS exercise, Fielded systems under an AFWERX SBIR contract with the 30th Security Forces Squadron at Vandenberg Space Force Base, Six-month combat deployment on the front lines in Ukraine with ground troops

## Products & services

- **Scout** — A deployable, palm-sized passive RF sensing platform with low size, weight, power, and cost (SWaP-C). It listens for the control signals between drones and operators without transmitting anything itself, detects drones up to roughly 3 km away, and feeds real-time data to the intelligence platform. Designed to be attritable for persistent presence.
- **Mosaic** — A distributed mesh network of Scout sensors for wide-area, persistent drone detection in austere and contested environments. Triangulates the position of drones and their operators, integrates with SpaceX Starlink for low-latency communication, and operates in degraded or high-interference conditions.
- **Intelligence Platform** — Software that converts raw RF detections into structured digital events that persist, correlate across locations, and form a shared operational picture. Integrates with operational systems such as TAK.
