PNT Situational Awareness
PNT Situational Awareness

Recommendations

To implement this framework, I propose the following recommendations that address the identified gaps and challenges. These recommendations provide a roadmap for building a comprehensive PNT-SA capability at organizational and national levels.

Establish PNT Situational Awareness Hubs

  • These hubs should serve as central nodes for data aggregation, threat assessment, and cross-sector communication.
  • They should maintain real-time monitoring infrastructure, such as ground-based GNSS monitoring stations, to act as a single point of truth for stakeholders.

Codify Cross-Domain Dependency Mapping

  • National infrastructure planning should institutionalise the modelling of PNT interdependencies. For instance, a dependency map might reveal that a power grid's timing system relies on GNSS, which in turn depends on satellite cybersecurity measures.
  • All critical infrastructure risk assessments should include a PNT dependency (and cascade assessment) audit, ensuring operators understand their vulnerabilities.

Develop SA Literacy Across Sectors

  • PNT-SA principles should be included in executive training, operator certification, and infrastructure planning and preparedness.
  • Cross-sector education initiatives should improve awareness of cascading impacts, using case studies.

Embed PNT-SA Functions in Regulatory Standards

  • PNT-SA functions should be required in resilience assessments and reporting mechanisms.
  • Best Practices should be formulated and adopted, and where necessary, minimum standards/requirements for detection, response, and recovery capabilities should be established, ensuring all sectors meet a baseline level of preparedness.

Align Investments with Resilience Informed by PNT-SA

  • PNT-SA-derived assessments and projections should prioritise infrastructure hardening and R&D funding. For example, simulation models might identify a need for Terrestrial RF system deployment in a specific sector, necessitating collaborative research between industry and academia.
  • Pilot programs and testbeds should model resilience under realistic conditions, such as simulating a GNSS outage during a NATO exercise to test response and recovery mechanisms.

Conclusion

Achieving resilient PNT services in the 21st century requires more than signal redundancy—it demands a strategic PNT-SA capability embedded at organisational, national, and international levels. By integrating Endsley's SA model with PNT resilience pillars, this essay creates a system where detection, response, recovery, and adaptation form a continuous loop, empowering institutions to anticipate, understand, and manage disruptions.

PNT-SA must evolve from an engineering detail to a national resilience function, enabling governance of systemic vulnerabilities with foresight and agility. As threats to PNT systems continue to evolve, this framework provides a roadmap for building a future where critical infrastructure is not merely reactive but adaptive, ensuring the stability and security of modern societies.
