ICARUS ENGINEERING

We build the systems
that fly the systems.

One avionics lineage. From orbit to air.

Prime in space. ReaperOS in air. ENKI around the engineering lifecycle.

ENKI · AI-native engineering copilot

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

ENKI spacecraft engineering · live 6U EO bus, 550 km SSO, 15 W payload at 35% duty. Size power and sketch the bus. BUS bus-geometry 3 computed values PWR spacecraft-power-budget 6 computed values MAS mass-budget mass margin within cap Eclipse is 5.8% of the orbit, so the array stays small — 17.6 W EOL over 0.064 m², with a 5.1 Wh battery at 30% depth of discharge.
