| Satellites operating in Low Earth Orbit (LEO) face a demanding environment, where electronic systems must withstand radiation, vacuum, wide temperature variations, and strong mechanical stresses during launch and operation. Traditionally, these systems rely on space-qualified components certified under standards such as MIL-STD-883 or ESCC, which ensures reliability but results in high costs and long procurement times.
This thesis focuses on the upscaling of commercial off-the-shelf (COTS) electronic components, establishing a methodology to evaluate their suitability, durability, and expected operational lifetime when exposed to space-representative conditions. The research aims to determine the feasibility of reducing costs in LEO satellite systems without compromising mission reliability beyond acceptable thresholds. The work plan is summarized as follows: Literature review and context: Study existing qualification standards (MIL-STD, ESCC) and identify the dominant environmental factors affecting electronic components in LEO, including radiation, temperature extremes, vacuum, and launch-induced mechanical loads. Component selection and classification: Build upon previous work to identify representative COTS components and classify them according to their role and criticality within satellite systems. Design of experimental procedures: Define test protocols to replicate key environmental conditions using available university facilities, focusing on thermal cycling, vacuum simulation when possible, and vibration/launch stress profiles. Execution of selected tests: Carry out environmental tests such as repeated thermal cycling or vibration and evaluate the functional performance of the components before and after testing. Lifetime estimation and modeling: Use accelerated aging models combined with LEO radiation environment data to extrapolate operational lifetimes for the tested components. Conclusions and recommendations: Propose a practical and reproducible methodology for the upscaling and validation of non-space-qualified components for LEO satellite missions |
