Three Stages for Achieving PNT Resilience in Critical National Infrastructure

The Royal Institute of Navigation promotes three stages of PNT resilience against disruptions. All organisations are strongly recommended to follow our guidelines in order to adequately prepare for PNT disruptions, act effectively and promptly when disruptions occur, and recover swiftly and with a goal of further improving their preparedness for future disruptions. In this manner a continuous cycle of improvement is adopted. This section provides richer information on the recommended best practices for carrying out these three core principles of resilient PNT.
