The new Position, Navigation and Timing (PNT) framework, unveiled by the UK government in October 2023, aims to safeguard critical services from satellite data disruptions. This framework is crucial for sectors that rely heavily on PNT information, such as finance, defence, transportation, telecommunications, and emergency services.
The framework outlines ten key measures to enhance PNT resilience, including:
Establishing a National PNT Office: A dedicated government unit will be created to oversee PNT resilience efforts and coordinate with relevant stakeholders.
Bolstering backup plans: In case of regular navigation system failures, such as Global Navigation Satellite Systems (GNSS), backup plans will be strengthened to ensure uninterrupted service delivery.
Investing in alternative technologies: The government will explore and invest in alternative PNT technologies, such as precise clocks and new satellite-based systems, to diversify PNT sources and reduce reliance on a single system.
Enhancing international collaboration: The UK will collaborate with international partners to share best practices and develop common standards for PNT resilience.
Raising awareness and training: PNT resilience awareness will be raised among critical infrastructure operators and relevant personnel to ensure effective preparedness and response.
Conducting regular risk assessments: Regular risk assessments will be conducted to identify and mitigate potential PNT disruptions and their impact on critical services.
Implementing PNT redundancy measures: Critical infrastructure will be equipped with PNT redundancy measures to minimize the impact of disruptions.
Fostering innovation: The government will encourage innovation in PNT technologies and applications to enhance resilience and security.
Promoting public understanding: Public awareness of PNT and its importance will be promoted to foster greater understanding and support for resilience efforts.
Conducting ongoing research: Continuous research and development will be pursued to advance PNT technologies and resilience strategies.
The implementation of this comprehensive PNT framework will significantly enhance the resilience of critical services against satellite data disruptions, ensuring the continued delivery of essential services to the public.
