Guardian Rf

Guardian RF builds passive, radiofrequency-based drone detection systems to counter the rise of low-cost commercial drones threatening U.S. national security. Off-the-shelf platforms now deliver ISR, contraband, and payloads while operating below radar coverage and beyond line-of-sight. These systems—often under neutralize multi-million-dollar assets. Scalable detection demands sensors that meet the threat in cost, size, and speed. Our systems are hardened for real-world deployment across military bases, public safety agencies, and critical infrastructure. We operate under an AFWERX Direct-to-Phase-II SBIR with the 30th Security Forces Squadron at Vandenberg Space Force Base. Our technology is fielded by law enforcement, integrated into fortune 500 commercial security teams, and selected for Falcon Peak 25.2—DoD’s flagship counter-UAS exercise. Scout is a passive RF sensor that detects and classifies drone control signals—including modified variants of DJI, Crossfire, and ExpressLRS—at standoff ranges. Mosaic extends coverage into austere environments, enabling low-altitude monitoring of non–Remote ID drones without active emissions or mesh dependency. All systems integrate with TAK and operational APIs, and are managed through GRF-SECURE for live alerting and forensic review. Guardian RF is U.S-built, cost-aligned, and designed for persistent defense of the homeland.
