Thermal Control System

Parent: REC-0001

Description

Adversaries seek a working map of the thermal architecture and its operating envelopes to anticipate stress points and plan timing for other techniques. Valuable details include passive elements (MLI, coatings, radiators, heat pipes/straps, louvers) and active control (survival and control heaters, thermostats, pumped loops), plus sensor placement, setpoints, deadbands, heater priority tables, and autonomy rules that protect critical hardware during eclipses and anomalies. Artifacts often come from thermal math models (TMMs), TVAC test reports, heater maps and harness drawings, command mnemonics, and on-orbit thermal balance procedures. When correlated with attitude constraints, payload duty cycles, and power budgets, this information lets a threat actor infer when components run close to limits, how safing responds to off-nominal gradients, and where power-thermal couplings can be exploited. Even small fragments, such as louver hysteresis or a heater override used for decontamination, can reveal opportunities to mask heating signatures or provoke nuisance safing.

Mappings

EU regulation articles

  • eu-space-actArt. 80(3)
    addresses
    moderate
    direct

    Thermal control system internals (TMM models, heater maps, autonomy rules) are operator-held artifacts whose disclosure reveals stress points; 80(3) places confidentiality categorization on this information.

  • nis2-implAnnex 12.1.1
    addresses
    moderate
    derived

    Thermal architecture envelopes, set-points and survival heater configuration are engineering-asset content whose classification governs storage and disclosure constraints.

  • nis2-implAnnex 12.2.1
    addresses
    moderate
    derived

    Handling-of-assets policy governs how thermal control documentation moves between integrators and contractors, which is the leakage surface for thermal reconnaissance.

ENISA controls

  • ENISA-STL-2025-03-sD.24-i01
    addresses
    moderate

    Information classification and labelling governs the protection of thermal math models, TVAC reports, and heater maps that REC-0001.05 targets, establishing handling rules rather than actively defending against collection.
