RUNE Sim

RUNE Sim (Realistic UAV Navigation Environment) is a customized Unreal Engine 5 simulation environment for training, testing, and validating autonomous systems in photorealistic defense and security scenarios. It is purpose-built to exercise Runic Defence's GPS-denied navigation (Raven Nav) and autonomy in controlled, repeatable conditions before field deployment.

It renders operations over real-world 3D terrain streamed for any location on Earth, with high-fidelity photoreal reconstruction of the operational area. A live digital twin visualises an entire drone fleet in motion — telemetry, position, and sensor readings updating in real time — and drops visual markers when sensors report anomalies such as smoke, fire, or gas, so operators can rehearse multi-drone missions exactly as they would unfold in the field.

It provides configurable sensor models — cameras and onboard imagery matched to real platforms — and threat emulation, so perception, navigation, sensor fusion, and decision logic can be exercised against realistic environmental and adversarial conditions.

RUNE Sim also supports hardware-in-the-loop (HITL) testing: a real flight controller running its actual firmware connects to the simulator, which streams synthetic IMU, GPS, velocity, altitude, and rangefinder data and reads back the controller's motor outputs to close the loop — so guidance, navigation, and flight-control behaviour can be validated on real hardware before any physical flight.

Build custom mission scenarios — urban operations, reconnaissance, search and rescue, perimeter surveillance, base protection, and complex multi-system coordination — and run them as often as needed at no risk to people or equipment.
