Key Terms
positioning, navigation and timing (pnt)technical
Positioning, navigation and timing (PNT) is the combined capability that tells devices where they are, how to move from one place to another, and provides precise time signals—think of it as a digital map, compass and clock all in one. Investors care because modern transportation, communications, finance and critical infrastructure rely on PNT; disruptions or improvements can change costs, risks and competitive advantage across many industries, like cutting power to a central clock in a city.
critical national infrastructure (cni)technical
Critical national infrastructure (CNI) are the networks, facilities and services—like power grids, water supply, transport, telecoms and banking—that a country depends on to function. For investors it matters because these assets face special government rules, higher security and continuity expectations, and potential for greater scrutiny or support; think of CNI as a country’s backbone, where failures can cause outsized financial, legal and operational consequences.
gnsstechnical
GNSS stands for Global Navigation Satellite System, a network of satellites that provide precise location and timing information anywhere on Earth, like a constantly available digital map and clock. It matters to investors because many industries—transportation, agriculture, telecom, finance and defense—rely on this positioning and timing for products, services and critical infrastructure; improvements or disruptions in GNSS can change costs, create new revenue streams, or introduce operational risk.
spoofingtechnical
Placing fake buy or sell orders with the intent to trick other market participants and then canceling them before execution; the goal is to create a false impression of demand or supply and move a security’s price. Think of it like pretending to bid at a yard sale to make an item seem more desirable, then backing out — it can mislead investors, distort prices and trading volume, and lead to regulatory enforcement and financial losses.
navigation innovation and support program (navisp)regulatory
A navigation innovation and support program (NAVISP) is an organized initiative—often run by a government or industry consortium—that funds, tests, and helps commercialize new navigation technologies and services for ships, aircraft, vehicles, or satellites. Think of it as an incubator and road-testing lane for positioning, guidance and related systems: it reduces technical and regulatory risk, speeds adoption, and can create business opportunities for suppliers and service providers, which matters to investors assessing future revenue and competitive advantage.
Project establishes innovative test framework to help UK operators, providers and suppliers adopt best practice and benchmark success
PAIGNTON, United Kingdom--(BUSINESS WIRE)--
Spirent Communications, now part of Keysight Technologies, a leading provider of test and assurance solutions for next-generation devices and networks, today announced it has partnered with the European Space Agency (ESA) to lead an initiative aimed at increasing the resilience of Positioning, Navigation and Timing (PNT) systems used in Critical National Infrastructure (CNI). The initiative will see Spirent and partners deliver a comprehensive test framework designed to drive measurable resilience in PNT systems for users, operators and providers of CNI in the United Kingdom.
The new initiative, supported by Element 2 of ESA’s Navigation Innovation and Support Program (NAVISP), is designed to raise awareness and improve resilient PNT test and assessment by providing a pathway to assess, validate and rate PNT equipment and services used in critical national infrastructure. With the 2023 UK Government report The Economic Impact on the UK of a Disruption to GNSS* estimating a 7-day GNSS outage could cost the UK economy £7.6 billion, the importance of the new initiative is clear, with CNI heavily dependent on satellite-based PNT systems and data.
“The increasing reliance on PNT underpins operations that people and businesses rely on every day,” said Mark Holbrow, Vice President of Engineering and Product Development at Spirent Positioning. “But for years, organizations have been wrestling with a fundamental challenge: they know PNT resilience matters, but they do not have a clear way to measure it or benchmark their progress. This new initiative changes that by building the tools and frameworks that let critical national infrastructure operators quantify resilience, track it, and improve it over time, and we're proud that ESA has entrusted Spirent to lead this exciting three-year project.”
The new initiative will support the UK Government's Resilient PNT Strategy by enabling access to rigorous, quantitative test evidence and operational insights that help evaluate and validate PNT systems across essential sectors. It will comprise three core components:
Spirent PNT Alliance – bringing together companies, academic research partners, and PNT professional and government bodies to identify, develop and cater resilience services for CNI.
PNT Shopfront - showcasing solutions that aid the adoption of resilient PNT and help to assure regulatory compliance for critical PNT dependencies.
PNT Resiliency Health Check – to enable independent appraisal of GNSS equipment capability against general performance, resilience, and security criteria.
The Spirent PNT Alliance will include the Royal Institute of Navigation (RIN) and other strategic partners to complement their activities and help build a resilient PNT ecosystem in the UK by commercializing best practices and connecting CNI operators with new technologies and test approaches. The annual PNT Health Check assessments will help organizations understand their dependencies, identify vulnerabilities, and track improvements over time, with a technical framework that scores resilience against standard benchmarks to create a pathway toward industry-wide test methodologies.
“Intentional and malicious disruptions to GNSS are now a daily occurrence, and are pervasive in the aviation and maritime sector,” said Director of the Royal Institute of Navigation, Dr. Ramsey Faragher. “The Royal Institute of Navigation is focused on raising awareness to these issues and in promoting the needs for improved resilience against such disruptions, especially within Critical National Infrastructure. Our Best Practice Guidelines emphasize the criticality of thorough testing in order to verify resilience and to help protect against both existing and future attack vectors. The UK is well placed to take a lead in this area, and well placed to inspire other nations to follow suit. We are really pleased to see initiatives like these from our corporate partners, and we look forward to supporting them.”
CNI operators in the UK finance, energy, and telecommunications sectors are increasingly recognizing vulnerability to GNSS jamming and spoofing, and will benefit from the development of the new framework, while the project also has strong export potential, positioning the UK as a leader in PNT resilience testing services.
