Demo: Satellite ADCS, bus shutdown prediction with coupled physics warm start recovery


Cover of Demo: Satellite ADCS, bus shutdown prediction with coupled physics warm start recovery

Niva’s Satellite ADCS Shutdown and Recovery is live on the Demos page. The demo, a web-based example of Manifold’s capabilities, runs a three-phase narrative: calibration, where live sensors feed Manifold's physics parameters; dark window, where coupled orbital, attitude, and thermal physics propagate deterministically through the shutdown; and recovery, where the predicted state is handed to the ADCS as a warm start. A side-by-side comparison shows warm-start recovery against conventional cold-start recovery on the same shutdown event.

What the demo does

  • Three-phase visualization with timeline scrubber: calibration, dark window propagation, recovery.
  • Selectable scenarios spanning different orbits, shutdown durations, and tumble rates.
  • Live calibration view: drag coefficient, atmospheric density scale, and magnetic dipole components calibrated from sensor telemetry against published spec values.
  • Telemetry panel surfacing star tracker, IMU, GPS, magnetometer, thermistor, and reaction wheel state.
  • Recovery comparison: Manifold warm-start vs conventional cold-start, with attitude error and along-track error tracked against an independent reference.

Why this is significant to space operators

Conventional ADCS recovery after a bus shutdown requires rate damping, star tracker search, GPS acquisition, and filter convergence, a sequence that typically takes 5 to 12 minutes. During that window, the spacecraft cannot point at Earth, its communications target, or its science observation. For an Earth observation constellation passing over a target, that recovery window is mission availability lost.

Manifold's coupled physics engine propagates the spacecraft's attitude, orbit, and thermal state through the entire shutdown window deterministically, on the spacecraft, without ground-in-the-loop. When the bus comes back up, the ADCS receives a predicted state with bounded uncertainty rather than starting from scratch. Recovery drops to under 2 minutes. Multiplied across a constellation and across shutdown events per year, the recovered availability is significant.

This is a direct instance of the architecture described in our orbital coupling-chain paper: runtime coupled physics, deterministic commits, edge deployment. The demo is what that architecture looks like running.

One platform, multiple domains

Satellite ADCS is one slice of what Manifold does. The same architecture runs satellite thermal analysis at 43 ms, polymer certification at 143 ms, and contact-rich robotic manipulation at 60 Hz. Different domains, same platform: constitutive physics that runs continuously, deterministic solvers producing every state transition, with sensor data refining the world model.
