Detect stealthy threats with Chorus
Passive air-acoustic sensor
Chorus detects aircraft that radar and RF sensors miss, from their sound alone.
How Chorus works
A Chorus sensor detects the air vibrations made by aircraft and other motorized vehicles, as well as gunshots. Chorus detects aircraft that emit no RF at all, including fiber-optic drones, autonomous drones, and manned radio-silent airplanes. Additionally, Chorus detects FAA Remote ID broadcasts from complying drones in the United States.
Detection range
| Method | Target | Max distance (meters) |
|---|---|---|
| Acoustic | Mavic-sized (Group 1 UAS) | 200 |
| Shahed-sized (Group 3 UAS) | Contact us | |
| Manned ground vehicles | Contact us | |
| Gunshots | Contact us | |
| Cooperative RF | FAA Remote ID1 | 1,000 |
1 The FAA Remote ID transmitters on most consumer drones typically do not transmit with enough power for long range detection.
