The $1B/day figure for losing #GPS comes from a discredited study — and it undersells the risk. Losing #GNSS would be a near-existential crisis for the U.S.

The UK's National #PNT Office wants to know who depends on the MSF 60kHz #timing signal. Call for evidence closes 11:59pm, 22 December 2026.

Thieves took $100M+ in data center freight — one case used #GPS #spoofing to beat tracking. Owning a spoofer isn't illegal in the U.S.

A study at @GeorgiaTech of 367,000 ships found 31 zones of #GPS anomalies — 22 with strong evidence of large-area #spoofing, including Red Sea activity before the MSC Antonia grounding.

Canada's new PNT Resilience Framework names over-reliance on #GNSS a single-point-of-failure risk — and starts with a National #PNT Office.

A 15-year, $6.27B #GPS ground-control program was canceled without ever reaching operations. @USSpaceForce's answer: a commercially sourced, ground-first GPS Gen4.

Space Force plans global deployment of up to 56 satellite-#jamming systems — a reminder that #GPS and other signals from space can be disrupted.

PNT is a preparedness problem, not just a navigation one: jamming, spoofing, cyber interference and space weather can all take down the trusted #timing that telecoms, finance and emergency response run on.

The Pentagon's FORTRESS America program would harden installations against cyberattack, sabotage, grid failure and supply disruption — but resilient #PNT is the foundation underneath all of it.

The UK now advises shipping to prepare for #GNSS-denied ops — official figures put a seven-day outage at £1.5Bn to the maritime sector, £1,309m of it in port operations.

38 people died after GPS #jamming reportedly disabled the ADS-B that would have identified Azerbaijan Air 8243 as friendly. What has aviation changed since?

GAO again finds only marginal #PNT progress and coordination gaps across DOD. The House 2027 NDAA would go further, with a senior official coordinating all DOD PNT efforts and reporting to the Deputy Secretary.

@FCC proposes auctioning 25 MHz of mid-band spectrum in 1675–1695 and 2020–2025 MHz, while @ntiagov asks for comment on protecting the #GPS L1 signal from D2D equipment.

"GPS-free" celestial navigation practice aboard CGC Eagle took its time hack from a system that gets its time from #GPS, a sign of how invisible the dependency has become.

Aviation may be the sector most affected by #jamming and #spoofing — and before GPS, ICAO listed Loran as an aviation system. A new opinion piece makes the case for restoring #eLoran as resilient PNT for aviation.

We understand @faanews regulations for UAS make little to no mention of #PNT — yet #UTM depends on good location and navigation data to manage low-altitude drone flights safely.
