Know what is flying over your facility.
Air Terminal listens for the radio emissions drones and their controllers already broadcast. It identifies the platform family, decodes FAA Remote ID, and alerts your security operations in real time. Receive-only: no jamming, no transmission, lawful for any private or commercial operator.
Why passive detection
Active countermeasures such as jammers and signal takeover are restricted under federal law to a small set of authorized agencies. A receive-only sensor carries no such restriction. Air Terminal emits nothing — there is nothing to license, nothing to interfere with, and nothing for a drone operator to detect.
Legal everywhere
Lawful for any private or commercial customer. No FCC spectrum license, no special authority, no legal review cycle before deployment.
Emits nothing
Strictly receive-only. It cannot interfere with site radios, Wi-Fi, or aircraft, and its presence cannot be detected by the operator.
Works air-gapped
Classification runs on the on-board edge AI. No cloud dependency, no data leaving your network, no subscription required for core detection.
Two pieces, one cable
A weatherproof mast head unit carries the antennas and RF front end at the top of a pole. An indoor compute unit carries the software-defined radio and NVIDIA Jetson edge AI. A single PoE++ run connects it to your network, and detections reach your VMS over a REST API and live WebSocket feed.
- Detect — control, video, and telemetry emissions, 700 MHz to 6 GHz
- Identify — platform family by RF signature, plus FAA Remote ID decode
- Alert — real-time to your VMS or security operations center
- Log — on-unit evidence trail with timestamp and signal data

- Sourcing
- Designed and assembled in Colorado, USA; NDAA-conscious component sourcing
Air Terminal is a passive receiver. It does not jam, take over, or disable aircraft. Detection covers UAS that emit RF, including their controllers; fully autonomous, RF-silent aircraft require complementary radar or optical sensors, which HPSI’s multi-sensor roadmap addresses.
