"PNT is the bedrock for virtually all modern-day activities from finance to transport that depend on access to reliable and accurate information. Examples cited include satellite navigation services that help people get from A to B, but also timing signals - without which mobile phones and even stock markets could not function properly. Indeed, the UK government cited a study showing that just a 24-hour outage of satellite navigation services could cost the UK economy £1.4bn."
"Yet the UK government warned that recent years have shown the threats posed by the jamming or spoofing of PNT services by hostile actors, and PNT can even be impacted by natural events like solar flares from the sun. It stressed that in what it called "an uncertain world" where the threats to PNT are growing, the UK cannot be complacent."
The UK will invest £155m to boost resilience and global leadership in positioning, navigation and timing (PNT) services. A Russian spy ship operating close to UK territorial waters illustrated how hostile activity can threaten communications and PNT. PNT underpins finance, transport, satellite navigation and timing signals essential for mobile phones and stock markets; a 24-hour satellite navigation outage could cost the UK economy £1.4bn. Secure PNT supports high-growth sectors such as AI and data and delivery of public services. Growing threats include jamming, spoofing by hostile actors and natural events like solar flares. Strengthened PNT capabilities aim to guide industry growth, support the economy and cement UK leadership.
