The Fremont hardware-in-the-loop laboratory provides dual-jetson real-time execution of the deterministic cyber-physical bridge, streamed live over an encrypted link
The reference hardware testbed operating in Fremont, california, bridges Silicon Valley engineering rigor with domestic Indian deployment. The testbed consists of two interconnected nvidia Jetson computing boards operating in an air-gapped configuration.
Board one is an nvidia Jetson nano running the non-deterministic autonomous mission planner, executing neural vision algorithms and trajectory proposals. Board two is an nvidia Jetson orin running the real-time deterministic cyber-physical safety bridge, enforcing formal mathematical containment and recording telemetry.
The rig executes real physical flight code under hardware-in-the-loop simulation. While the aircraft aerodynamics and environmental wind gusts are simulated in a mathematical physics engine, the control commands, serial bus packets, and safety gate calculations run on real embedded silicon.
The deterministic gate intercepts control commands every five milliseconds. If the mission planner proposes a trajectory that violates aerodynamic limits or approaches a virtual geofence, the gate mathematically truncates the vector, substituting an optimal tangential braking vector.
The Fremont laboratory is integrated into a secure, encrypted mesh network via tailscale, linking the testbed directly to the Pune innovation summit and c-dac workstations.
During the live summit demonstration, attendees in Pune witness real-time teleoperation over the transatlantic link. Attendees observe the simulated drone attempt to breach the geofence under aggressive adversarial steering, demonstrating the unbreakable mathematical boundary enforced by the bridge.
