Onboard autonomy

Vision belongs on the aircraft.

Perception at the edge. Control at the core.

The perception stack is designed onto the flight platform itself — beside the sensors that feed it and the controller it serves.

SpaceICARUS Prime

AirICARUS ReaperOS

Shared primitives. Domain-specific assurance.

ICARUS ReaperOS began as a fork of ICARUS Prime, then diverged for the timing, interfaces and assurance requirements of uncrewed aircraft — shared architecture, primitives and tooling; its own evidence, its own safety case.

Primary flies. The reserve perceives — and carries non-critical, compute-heavy work the primary offloads: bounded, asynchronous, discardable. Every motor channel holds its own limits.

After a confirmed primary failure, the reserve sheds perception and assist work and takes authority as warm backup — classical control code, through a hardware-isolated, latched path. Takeover is physical, and under validation.

With both upper layers silent, the four Safety ESC Controllers remain as the final layer — a prevalidated distributed-survival behaviour, closest to the hardware.

// ESC = electronic-speed-control channel — each is also the local safety supervisor for its motor.

ENKI · AI-native engineering copilot

The aircraft is only half the system.

ENKI — HawkLogic’s AI-native engineering copilot — is live today for spacecraft engineering. The same system-native architecture is being extended natively into ICARUS Reaper.

A general-purpose AI starts with context. ENKI starts with the system.
