Lighthouse AvionicsBorn from a Hilliard police chief’s effort to bring Drone First Responder operations to Ohio, Lighthouse Avionics builds passive airspace-awareness systems for counter-drone security, remote towers, and beyond-visual-line-of-sight flights. Founded in 2021, the Hilliard company developed its VICTOR platform from early radar and computer-vision work into deployable optical detection systems, including a remote tower operating at Springfield-Beckley Municipal Airport. Its dual-use technology serves public safety and commercial drone operators alongside defense and critical-infrastructure missions.COLUMBUS, OH
Hidden Level, IncFounded in 2018, Syracuse-based Hidden Level develops and manufactures passive radio-frequency sensing hardware, software, and data services that turn activity across the spectrum into airspace intelligence. Its U.S.-made systems detect and track crewed and uncrewed aircraft—including RF-silent targets—for defense, public safety, and critical-infrastructure applications. The company now operates four Syracuse facilities, including an advanced manufacturing campus with an anechoic chamber for in-house system testing.SYRACUSE, NY
Guardian RFGuardian RF grew out of a group of Georgetown University classmates studying physics and signal processing, whose work took them into Ukraine supporting local defense units. The Washington, D.C., company now develops passive RF sensing technology for persistent low-altitude airspace awareness, serving defense and public-safety organizations without emitting signals.TEMPLE HILLS, MD
