Detect. Decide. Neutralize. Unattended.
A decoupled edge architecture — a Brain and a Body — that runs the entire kill chain with zero human in the loop and zero cloud.
The system in the field.

Walk a threat through the chain.
Drag the slider to move a hostile track toward the perimeter. Each stage executes on-device — no cloud, no RF link, no operator.
Edge-AI Fusion & Tracking
- NVIDIA Jetson Orin AGX / Orin NX ruggedized compute
- ROS 2 middleware, TensorRT Int8/FP16 inference
- Dual CMOS/LWIR thermal ingestion, PTP time-sync
- 3D Extended Kalman Filter fusion, ≤15ms per-frame inference
- Auto-switches to thermal when optical contrast drops
Real-Time Actuation
- STM32H7 (Cortex-M7) MCU on FreeRTOS, ISO-C / Rust
- Field-Oriented Control on high-torque BLDC gimbal
- 100 Hz target command bus (CAN-FD / isolated Ethernet)
- 100ms watchdog → instant "Safe Hold" cutout
- Multi-stage Ready → Armed → Fire handshake
Engineered for the kill chain.
Switch the protocol to inspect each subsystem. Every layer is modular — if optical fails, thermal keeps tracking.
Optical + thermal fusion & EKF
Dual optical + LWIR thermal streams are fused through a 3D Extended Kalman Filter. PTP hardware timestamping prevents drift during coordinate extrapolation, and predictive intercept math generates live turret vectors. No radar = no RF emissions, no export controls.
- Inference latency≤ 15 ms
- Time syncPTP / IEEE 1588
- Sensor mixCMOS + LWIR (no radar)
Edge-AI object classification
Quantized Int8/FP16 models on the Jetson classify Micro-UAV, Fixed-Wing, Bird and Aircraft with zero cloud reliance. The system auto-blends to thermal when optical contrast collapses — night, fog, or dust storms.

Real-time kinematic control
A 100 Hz command bus drives FOC BLDC pan-tilt motors with absolute magnetic-encoder feedback. A 100 ms watchdog cuts power to "Safe Hold" on Brain loss, and geofencing prevents the mechanism from striking its mount.
