Sentac is a self-contained passive RF detection system built for dismounted troops — no network required, no infrastructure, no procurement cycle measured in years.
Get in touchFPV drones cost $200 and are on every modern battlefield. Current detection systems cost tens of thousands of dollars, weigh kilograms, and require connectivity that doesn't exist at the squad level.
The soldier who needs to know a drone is coming is the last person the current market is serving.
Purely passive RF detection. Sentac never transmits — making it undetectable to the threat it is monitoring.
Fully self-contained. No connectivity required, no infrastructure dependency, no single point of failure.
Designed to integrate with existing soldier kit. Lightweight enough that every soldier can carry one.
Most detection systems are designed around commercial DJI-class drones with GPS and telemetry. The drone killing soldiers today is a $200 FPV racer running FrSky or ExpressLRS.
Sentac is built specifically for that threat profile — covering the frequencies actually used on today's battlefield, not the ones that are easy to sell against.
Lightweight enough to be on every soldier. Affordable enough to actually get there.
One device per squad isn't enough. Detection needs to be individual, persistent, and passive — present at the point of threat without adding burden to the mission.
Sentac is designed to integrate with existing wearable soldier systems — worn, not carried. On when you are. Off when you're not.
Sentac is currently engaging with select partners for early evaluation and integration. We are not a general commercial product — we are built for the operators who need this most.
If you're working on the same problem, we should talk.
