AI design studio
Meet ENKI — design a whole mission by talking to it
ENKI is an AI spacecraft-design studio. Describe a CubeSat and it sizes the mission with you — running the calculators, tracking a live design state, sketching the bus in 3D, and explaining every number. It’s the fastest path from a rough idea to a sized, sanity-checked design.
-
Conversational design
Describe a mission in plain language; ENKI designs it with you, turn by turn.
-
Runs the real tools
It calls HawkLogic’s calculators as tools — the same physics the free tools run.
-
Live design state
Parameters and calculations collect in a running mission-design state.
-
Sees in 3D + charts
Sketches the spacecraft bus in 3D and answers with diagrams, charts, and math.
-
Checks itself
Auto-runs a constraints check each turn and flags violated margins and inconsistencies.
-
Picks up where you left off
Sign in and your design threads persist — resume a mission any time.
Free spacecraft calculators
Run the numbers, right in the browser
Twenty pure-physics calculators for the mission-design questions satellite teams keep asking — power, links, Δv, drag, radiation, compliance. Cited constants, no backend, free. Eighteen of them can explain their own output in plain English with a built-in AI explainer.
-
Spacecraft Power Budget
Solar array, battery, and power-system mass for a LEO mission.
-
Comms Link Budget
EIRP, path loss, C/N₀ and margin with ITU-R rain fade. S–V band.
-
Δv & Maneuver
Propellant and burn time for a maneuver from the rocket equation.
-
Deorbit & Lifetime
Check a disposal orbit against the FCC 5-year rule & ESA Zero Debris.
-
Radiation Dose
Total ionizing dose behind shielding over the mission lifetime.
-
Thermal Balance
Equilibrium temperature from absorbed flux and radiator area.
Products
Flight-ready when you are
Past the sizing tools, we build the production software that flies the mission. Start with ICARUS OS — more products are on the way.

ICARUS OS
Flight software for CubeSats
A deterministic CubeSat onboard-computer platform — a custom real-time operating system (RTOS) with space-standard CCSDS telecommand and telemetry, 5-level fault detection, isolation and recovery (FDIR), and memory-protection-unit (MPU) task isolation. ~68 KB flash, ~5.6K LOC on ARM Cortex-M7, with an open-source kernel.
- Custom RTOS · ~68 KB flash, ~5.6K LOC
- CCSDS telecommand + telemetry
- 5-level FDIR autonomous fault recovery
- Open-source kernel — icarus-os-core (Apache 2.0)
- In development
ICARUS Reaper Mark I
Integrated edge autonomy for uncrewed aircraft
HawkLogic's uncrewed-aerial-vehicle (UAV) line; Mark I is its first platform — one compact 8-layer board designed to carry what is normally a stack: deterministic flight control, onboard vision/AI compute, sensing, protected power, comms, and four motor channels with local safety enforcement — partitioned so no single compute path is the sole authority. In active development, architected to run ICARUS ReaperOS — the aerial-avionics OS forked from the ICARUS Prime lineage and specialized for uncrewed aircraft.
- One board replaces the companion stack — flight control + AI compute + four motor channels
- Onboard vision and neural acceleration — no companion computer, no cloud dependency
- Three layers of authority with hardware-isolated, latched takeover
- ICARUS ReaperOS — deterministic aerial avionics from the ICARUS lineage
How we think
Determinism
Flight software can't be statistical. Every cycle accounted for, every deadline met, every command dispatched on time. ITCM-resident hot paths and a hard real-time scheduler under the hood.
Safety
Hardware-level fault isolation across the whole stack. Per-task MPU regions, 5-level fault escalation, hardware CRC monitoring, SEU-tested, MISRA-C on the roadmap. Evidence, not promises.
Long-term
A mission is a long-term commitment, not a launch event. Ground-loadable configuration. State that survives resets. Built to keep flying reliably through contact gaps and the whole operational life.

How to build a CubeSat power budget: solar arrays, batteries, eclipse
Load tables by mode, eclipse fraction, solar-array sizing with EOL degradation, battery depth-of-discharge — and a worked 6U example you can reproduce.
When is my satellite overhead? TLEs, SGP4, and pass prediction
How a Two-Line Element set and the SGP4 propagator become ground-station pass windows — AOS, LOS, elevation masks, max elevation — and why TLE freshness is the whole accuracy story.
The FCC 5-year rule: will your CubeSat come down in time?
Orbital decay physics, ballistic coefficient, solar-cycle sensitivity, the FCC 5-year post-mission disposal rule, ESA Zero Debris, and remediation options.
