Challenges to national defence in contemporary geopolitical situation

This study proposes a time-synchronised airborne–ground semiconductor radiation measurement architecture for in-situ validation of space weather models in military aviation environments. The work defines a measurement research proposal using a JAS-39 Gripen platform equipped with a semiconductor detector and a ground-based reference system, rather than reporting results. The framework enables correlation of radiation measurements with space weather datasets, operational forecasts, and the AVIDOS dosimetric model for aviation radiation exposure. It supports model validation and improves characterisation of the aviation radiation environment. Overall, the research proposal enhances Space Domain Awareness by increasing availability of in-situ radiation data in flight conditions.
