HIL Testing
Hardware-in-the-Loop Testing for UAV Systems
Hardware-in-the-loop testing puts real UAV hardware under synthetic flight and sensor conditions, catching integration failures that software-only simulation cannot see.
How our HIL rigs work
A hardware-in-the-loop rig feeds synthetic sensor and flight data to real flight controller and payload hardware, so the hardware genuinely responds — including its timing, power draw, and failure behavior — while the surrounding flight environment is simulated. This lets us test failure modes (GPS loss, link degradation, sensor fault injection) that would be unsafe or impractical to test in open airspace.
Because the hardware is real, HIL testing catches integration issues — timing mismatches, power budget violations, firmware edge cases — that a pure software simulation of the flight controller would miss entirely.
From HIL testing to simulation calibration
Data captured during HIL testing does double duty: it validates the specific hardware under test, and it feeds the calibrated physics and sensor models inside Zone of War, so simulation scenarios built on that data reflect how the hardware actually behaves rather than how it is specified to behave.
Real hardware, synthetic environment
Flight controllers and payloads respond to real timing and power conditions.
Safe failure-mode testing
Test GPS loss, link loss, and sensor faults without open-airspace risk.
Feeds simulation calibration
HIL test data directly informs Zone of War's physics and sensor models.
