  Reliability-Aware Mathematical Model for Radiation-Hardened Satellite Communication Systems

  By Rosalin Pradhan, Sidhartha Kumar Samal, Sritam Parida, Bibhu Prasad Ganthia

  Abstract: Satellite communication systems operate in radiation environments in which total ionizing dose (TID), displacement damage, and single-event effects (SEE) can progressively degrade electronic, optoelectronic, and communication components and can ultimately reduce link availability and mission reliability. This paper develops a Reliability-Aware Radiation-Hardened Satellite Communication Model (R-RHSCM) that mathematically couples the orbital radiation environment, accumulated radiation dose, component degradation, communication-link performance, single-event failure probability, redundancy, thermal effects, and adaptive mitigation. The …
