This study addresses key issues related to the technical protection and restoration of critical railway infrastructure in the Czech Republic when dealing with military and non-military crisis situations. These issues can be divided into problems of organizational nature and technical problems. The study demonstrates how these key issues can be resolved and what steps are required. Ensuring the operational readiness of railway infrastructure is an integral part of successfully managing crisis situations and securing military transport, as well as transport for the national economy and the population.

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.
