Radio jammers and radar are the standard tools for stopping drones today, but both have a blind spot. A drone flying with no radio link cannot be jammed, and it cannot be found by equipment listening for a radio signal it never sends. Radar also struggles with something that small flying that low. That is the exact gap DroSonic was built to close, using acoustic signatures instead.
This week, the team took a working DroSonic prototype to DIRT Days 26.04, a field exercise supported by the Civil-Military Innovation Institute (CMI2) in partnership with U.S. Central Command (USCENTCOM) and U.S. Army DEVCOM. In an environment built to resemble a contested electronic battlefield, DroSonic heard drones where other sensors stayed blind.
What stands out most is the timeline. It took eight months to go from an early idea about propeller noise to a system tested against live drones in the field, and the prototype performed better than the team had asked of it.
None of this happens alone. The team thanks the CMI2 and DIRT Days organizers for the opportunity, along with Army PIT, the Colorado APEX Accelerator, Colorado SBDC serving Boulder County, and NVIDIA for Startups for their support along the way.
