Welcome to CORHA-2: Next-Generation COTS Reliability for Space Missions

 

Building on the success of its predecessor, CORHA, the CORHA-2 project is an ESA-funded initiative led by Seibersdorf Laboratories with the University of Padova. CORHA-1 initially set the groundwork by testing COTS components for radiation resilience and established RHA (Radiation Hardness Assurance) approaches to enable cost-effective, reliable use of commercial technology in European space missions​ [1][2][3][4].

CORHA-2, officially launched on October 31, 2024, expands this vision over three years, pushing the frontiers of reliability for COTS components through advanced radiation testing, database transparency, and AI-driven predictions.

 

 

1. Component Selection
   CORHA-2 focuses on selecting critical electronic components such as III-V semiconductors, data converters, memory devices, oscillators, and other high-demand technologies essential for space missions.
    
2. Advanced Radiation Testing
   Testing methodologies from CORHA-1 are refined and expanded in CORHA-2, which uses Total Ionizing Dose (TID) and Single Event Effects (SEE) testing with heavy ions and pulsed lasers to simulate space radiation effects on COTS.
    
3. Open Access Database
   CORHA-2’s radiation testing data will be available in a publicly accessible database, offering industry stakeholders detailed insights and promoting transparency.
    
4. AI-Enhanced RHA
   The project integrates machine learning to improve predictive accuracy, enhancing the efficiency of radiation hardness assurance processes.
    
5. Guidelines for Low-Cost Missions
   CORHA-2 builds on the foundational guidelines of CORHA-1, providing updated best practices for using COTS on low-cost space missions to support European space industry advancements.
