Satellite Computer Platform Prototype Development
Development, design and implementation of a fault-tolerant on-board computer prototype consisting of standard COTS technology. Developed a satellite bus simulation setup, consisting of multiple FPGA and microcontroller boards as a first stage. Then developed this into several generations of custom prototype PCBs which were then manufactured, populated, tested and integrated into the ecosystem. Built up a PCB manufacturing, assembly and test laboratory for this purpose. I constructed every part of this setup, which required two years of systems engineering, research into process optimization, material science, RF/high-frequency and low-noise electronic design and EMI/noise mitigation. In the process, I conducted serveral spin-off projects, e.g., collaboration with RIKEN researchers on SMD reflow and solder joint quality with optical and scanning electron microscopy (SEM), and the creation of an additive manufacturing setup. My objective has been to produce a viable prototype of the technology I invented. I have been successful, and the next step on this path is the founding of a company to commercialize this new technology.

Leiden University, The Netherlands
Ran an ESA funded research project to development of a novel approach to fault-tolerance for modern COTS electronics in space, using software-side measures and FPGA reconfiguration, and mixed criticality concepts. Collaboration with Leiden Observatory astrochemists on astrochemical models (numerical codes) for analysis of observations. Cooperation with the JWST-MIRI team in the preparation, debugging and testing for the MIRI Simulator. Based on MIRISim produced an example payload application for fault-tolerance proof-of-concept, which was later replaced with ESA NIRcam.
