Towards a Structural Framework for PNT Situational Awareness

Integrating PNT System Resilience and Human-Centric Situational Awareness for Strategic Infrastructure Protection

Andy Proctor – May 2025

Modern societies are deeply reliant on PNT services, yet this dependency is often poorly understood at the institutional level.

Integrating Endsley's SA model with PNT resilience functions creates a dynamic framework that enhances system-wide preparedness.

Despite the critical role of PNT systems, several weaknesses undermine the potential success of PNT-SA.

PNT-SA must be elevated from a technical process to a strategic capability embedded within organisational frameworks.

Building a structural PNT-SA function will confront several challenges including fragmented ownership and lack of literacy.

Establish PNT Situational Awareness Hubs, codify cross-domain dependency mapping, and develop SA literacy across sectors.
