Tenders are invited for Prognostic Methods for Re-Usability of Electronic Units - Expro plus. Reusability of launch systems and vehicles is a game changer for the space transportation industry. The assessment of the performance limit of electronic units to be reused is very complex. The current approach to process verification requires representative simulation of the sequence of events as there is limited understanding of the accumulative effects (launch, in-orbit exposure, re-entry,and multiple repetitions) on the overall reliability. This approach is lengthy and expensive. Especially in view of commercial competitiveness and innovation, an alternative approach needs to be developed to reduce costs and lead-time for process verification andelectronic unit qualification. Possible solutions for prognostic are canary devices/circuit, sensors and modelling. This activity encompasses the following tasks:- Literature review of prognostic techniques for Electronic Systems;- Design of suitable functionaltest vehicles including sensors and canary devices/circuits;- Implementation of test approach allowing to assess impact of different events/sequence on overall life of the test vehicle;- Development of models and approaches for performance prediction and in-situ health monitoring of electronic units;- Comparison of prognostics to other critical circuits on test board.
