GPS is one of those things we rarely notice - until it stops working. My book, Little Blue Dot, tells the story of how a Cold War military system became the invisible infrastructure behind modern life: maps, phones, trade, banking, farming, dating, takeaways and more. June 2026

I spoke with @piya on @CBC ’s The Sunday Magazine about the little blue dot that changed the world: how GPS went from a US military tool to something that now underpins almost every part of daily life and why it’s more vulnerable than we think cbc.ca/listen/live-ra…

From airliners to supertankers, GPS has long been invaluable for safe navigation, but its signals can easily be jammed and almost as easily faked. Researchers are racing to develop backups. theconversation.com/from-hormuz-to…

Really enjoyed talking to @Marketplace about Little Blue Dot and why GPS is now a pillar of the global economy - underpinning everything from navigation and trade to power grids and digital time. marketplace.org/story/2026/06/…

As GNSS threats continue to evolve, resilient Positioning, Navigation and Timing (PNT) systems are becoming essential for mission success. Join this free webinar on June 24 to hear industry experts discuss how defense organizations can move beyond a GNSS-first approach and build multi-layered PNT architectures capable of detecting, responding to and recovering from disruption in contested environments. Learn how to strengthen system resilience, improve situational awareness and prepare for the challenges of GNSS-denied operations.

Great read from @TerezaPultarova in @SPACEdotcom on the immense scale of GPS jamming across Europe and the Middle East and why the invisible signals we rely on for navigation, finance, power grids and satellites are far more fragile than they feel. space.com/space-explorat…

A new book argues that #GPS isn't just infrastructure — the battle over GNSS is a battle over truth. "Little Blue Dot" by Katherine Dunn traces the history from WWII to today's threat landscape. Now on sale. 🔗 rntfnd.org/2026/06/12/we-… #PNT #GNSS #CriticalInfrastructure

I’m on @BBCRadio4’s Start the Week tomorrow, talking to @TDS153 about Little Blue Dot and the hidden power - and fragility - of GPS in everyday life. 9am, alongside Baroness Beeban Kidron and @MeenaKandasamy. bbc.co.uk/programmes/m00…

Thanks to The @Telegraph for this! telegraph.co.uk/books/non-fict…

GPS has long been something we’ve trusted implicitly, but the technology that guides us through everyday life has opened up an alarming vulnerability. Journalist and author Katherine Dunn assesses the dangers of GPS spoofing: thewalrus.ca/how-to-hack-a-…

Quite overwhelmed and very flattered - to see Little Blue Dot given four stars in Saturday’s @Telegraph review. It’s a strange and lovely feeling to see something I’ve spent so long working on spread across two newspaper pages. Huge thanks to Christopher Webb for such a thoughtful review. 🛰️🌍

Russian satellites have been #jamming #GPS across Europe since 2019 — new research shows their reach could have covered all of northern Europe or the U.S. homeland. 🔗 rntfnd.org/2026/06/05/rus… #GNSS #PNT #Russia #NavWar

Great to speak to @hugorifkind on his always-fabulous @TimesRadio show today about all things GPS - a technology even Donald Trump probably uses on the golf course without realising it. You can listen back here from the 51:30 mark: thetimes.com/radio/show/202…

Mysterious 10-second GPS interference signals have been hitting Europe since 2019 — and researchers think Russia is to blame techradar.com/computing/a-ma…

A lovely first review for Little Blue Dot from @PublishersWkly, calling it a “riveting debut history” and “a fascinating account of a singular technology that changed humanity’s relationship to the world.” publishersweekly.com/9781639734313

GPS jamming is rarely about one aircraft. It creates a zone of uncertainty, exposing how much modern life assumes the signal will always be there.

Two dates for the diary: Little Blue Dot is out in North America with @BloomsburyPub on 16 June 2026, and in the UK with @HarperCollinsUK on 18 June 2026. Pre-order: UK: harpercollins.co.uk/products/littl… North America: bloomsbury.com/us/little-blue…
