Radiation-Induced SEUs Corrupt AI Weights

Under Mars Deep-Space GCR + X-Class Solar Proton Storms, 64 MB volatile AI weight SRAM on unshielded Al-6061 suffers 234 flips/day, silently corrupting attitude & fault control.

Thermomechanical & Detumbling Shocks

KÜPSAT-01 recorded ~20 G separation shock and 3,647.58 °/s tumble. Standard Al-6061/COTS buses freeze down to -141.5 °C internal temp and lose 64 Hz modal margin under 14.1 Grms.

KÜPSAT-01 Flight (421 Samples)

7 Aug 2026 mission: 22.51 hPa min pressure, -54.50 °C exterior vs -17.27 °C internal (+37.23 °C passive thermal differential).

IAC-26-C2.IPB.29 Structure

Al7075-T6 / CFRP + Hexagonal Honeycomb sandwich: 18.49 MPa von Mises, 0.254 mm deflection, Mode 1 = 100.76 Hz (GEVS 14.1 Grms), FS = 27.20.

1U Mass & Cost Advantage

Complete WERR Hybrid bus is 373 g (957 g payload margin out of 1,330 g 1U limit) at $8,300 total vs $42,800 for heavy 775 g Rad-Hard TMR avionics.

Immutable 24-Byte (192-bit) Mathematical Seed

• • 0 Bytes mutable weight SRAM (0.0 weight flips/day, 0.35 W ultra-low compute)
• • Deterministic arithmetic replaces 64 MB volatile neural matrices
• • Dual-byte hardware CRC-16/CCITT-FALSE catches 192 / 192 single-bit SEU corruptions at 100% accuracy

Dual-Stage Deep-Space Thermal Envelope

IAC passive MLI/honeycomb insulation (+37.23 °C gain) paired with a thermostatically regulated 0.50 W survival heater (0.85 W total bus in deep space) keeps internal electronics ≥ -24.5 °C (safe above -30 °C limit) at -150.0 °C ambient.

Schwarzian + Koenigs ADCS

Negative Schwarzian S(f)(0) = -6.919 < 0 & Koenig multiplier μ = 0.75 damp 3,647.58 °/s energy by 94.37% in 10 cycles vs PID 63.15% or SEU-degraded ARM 29.97%.

Patent 2 · Julia Watchdog

TR 2026/016633 hardware gate strictly vetoes unstable controller gains (|r| ≥ 2.4046) and locks μ = 0.75 before actuator saturation.

Patent 3 · Spoofing Barrier

TR 2026/020266 Collatz Parity Lyapunov barrier isolates injected spoofing bursts whenever γ = n_odd / n_even > 0.58496.
