SPACEPULSE™
Autonomous Spacecraft GNC Firmware & Deterministic Physical Governor
Modern satellite constellations and deep-space missions operate beyond the loop of ground teleoperation. While onboard AI agents excel at macro logistics and swarm tasking, stochastic neural models cannot be trusted with direct thruster authority.
SpacePulse solves the aerospace autonomy bottleneck. Operating as a deterministic, flight-grade physical governor in bare-metal #![no_std] Rust, SpacePulse sits strictly between autonomous AI planners and spacecraft actuators. It enforces closed-form orbital invariants, verifies keep-out zones, manages reaction wheel saturation envelopes, and guarantees zero unphysical maneuvers.
Why AI Planners Cannot Have Direct Thruster Authority
Modern mega-constellations cannot rely on human ground-station commands. But plugging neural networks directly into flight actuators is an unacceptable mission risk.
AI Hallucinations in Flight
Autonomous LLMs and cognitive swarm agents can miscalculate orbital perturbations, hallucinate unphysical slew paths through blinding solar keep-out zones, or exhaust fuel reserves in singular maneuvers. One unvetted burn can destroy an entire mission asset.
The SpacePulse Physical Governor
SpacePulse forms an unyielding boundary. Every high-level command is intercepted and mathematically vetted against instantaneous power budgets, structural thermal limits, propellant reserves, and Clohessy-Wiltshire relative drift envelopes.
Cybernetic Fallback Co-Pilot
When an unsafe command is vetoed, SpacePulse does not simply freeze. Its embedded fallback co-pilot automatically synthesizes a certified, physically optimal recovery maneuver—ensuring the satellite remains operational, stable, and power-positive.
Integrated Flight Capabilities
From Lie Group attitude kinematics to radiation fault-tolerance across the South Atlantic Anomaly.
1. Lie Group SE(3) & SO(3) Kinematics
Full quaternion kinematics utilizing Riemannian exponential and logarithmic maps, completely avoiding gimbal lock. Provides exact 6-DOF docking corridor monitoring combining approach cones and angular limits.
2. 4-Rate Cyclic Executive Scheduler
Static rate-monotonic executive executing 100 Hz rate-gyro loops, 10 Hz TRIAD/QUEST attitude determination, 1 Hz GPS/J2 ephemeris propagation, and 0.1 Hz CCSDS housekeeping beacon broadcasts.
3. Radiation Hardening & TMR Scrubbing
Bitwise 2-out-of-3 Triple Modular Redundancy (TMR) and (39, 32) SEC-DED Hamming error detection. Scrubbing rates dynamically scale up to 1000 Hz during orbital passage through the South Atlantic Anomaly.
4. Autonomous Collision Avoidance (CAM)
Automated Time to Closest Approach (TCA) and 2D B-plane Gaussian Probability of Collision (Pc) solvers that compute fuel-optimal Clohessy-Wiltshire evasive burns against space debris.
5. Rendezvous & Swarm Station-Keeping
Quasi-Nonsingular Relative Orbital Elements (ROE) and closed-form CWH dynamics for multi-satellite Walker-Delta constellation station-keeping and safe passive drift during proximity operations.
6. CCSDS Telecom & Science Payloads
Compliant with CCSDS 133.0-B-2 Space Packet Protocol and CADU frame synchronization. Features astrobiology payload pipelines evaluating chemical disequilibrium, homochirality, and planetary habitability indices.
