Jan Suchanek contributed to the CURocketEngineering/Avionics repository by enhancing the telemetry logging system and improving SD logging reliability. He implemented a launch-number-based file naming convention and added servo angle data to telemetry logs, enabling more precise flight data traceability and richer post-flight analysis. Using C++ and leveraging skills in embedded systems and file management, Jan addressed hardware interaction challenges by correcting SD card initialization pin usage, which improved logging stability and reduced data loss risk. His work also included adjustments to API visibility, laying the foundation for future integration and testing improvements within the avionics logging subsystem.
