Compute at the Speed of Flight.

Headless API SaaS Engine for Modern Astrodynamics & Spaceflight

Deterministic computational modules exposed as a pure machine interface — no console, no dashboards, no operator seat. Requests carry your state vectors in; certified mathematics and verification artifacts come back out. Nothing is retained on our side.

SECTION A

Operational Charter

FOUR FOUNDATIONAL PRINCIPLES · BINDING ACROSS EVERY MODULE, EVERY REQUEST, EVERY RELEASE.

CARD 01

Computational Proof

We certify the computation. You certify the inputs. Our math is provable. Your data stays your responsibility — and your property.

PROOF EMITTED
CARD 02

Zero Data Custody

Your data never leaves your side. Credentials, telemetry, mission files: stored here, never with us.

AT REST NONE
CARD 03

Invariant Physics

The physics cannot be switched off. Tier-0 variables sit beyond every password. Including ours.

TIER-0 LOCKED
CARD 04

Advisory Class

Advisory class. Mathematics is certified but not flight certified. We advise; you execute. Requires explicit FDO sign-off.

FDO SIGN-OFF REQUIRED

ADVISORY CLASS NOTICE

Outputs are advisory computational products. Mathematics is certified; the system is not flight certified and carries no airworthiness, launch, or operational authority. All maneuver, avoidance, and station-keeping decisions require explicit Flight Dynamics Officer sign-off within the operator's own certified process. Simulated or unpopulated parameters are surfaced as -- or UNKNOWN and must never be interpreted as nominal values.
