Report on Positioning, Navigation and Timing (PNT) resilience policies and strategies by The University of Tokyo and The University of Sydney

During his stay as visiting scholar at the Intelligent Space Systems Laboratory (Nakasuka-Funase Laboratory), Graduate School of Aeronautics and Astronautics, The University of Tokyo, Mr. Joshua Critchley-Marrows of the School of Aerospace, Mechanical and Mechatronic Engineering, The University of Sydney, collaborated with Assistant Professor Quentin Verspieren of the STIG program on a report on the concept of Positioning, Navigation and Timing (PNT) resilience.

PNT services have become the backbone of numerous vital infrastructures: banking and financial networks rely on space-based timing, various transportation services are fully dependent on satellite positioning, and so on. Any disruption of space-based PNT services, whether intentional or accidental, could have dramatic consequences for national security, public safety and economic security. In consequence, states owning and operating Global Navigation Satellite Systems (GNSS) have grown extremely concerned with the reliance of their infrastructure and its ability to provide stable and trustworthy PNT signals.

How did these concerns manifest themselves? What are the resilience considerations included in the PNT policies and roadmaps that have been adopted by major operators of GNSS and other spacefaring countries in recent years? This work proposes a review and comparative analysis of the main navigation policies and strategy documents in the United States, Canada, the European Union, Russia, the United Kingdom, India, Japan, Australia, Türkiye, China and South Korea, to ensure the resilience of PNT services.
