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. 🔗 rntfnd.org/2026/10/25/367000… #PNT #Maritime

Canada's new PNT Resilience Framework names over-reliance on #GNSS a single-point-of-failure risk — and starts with a National #PNT Office. 🔗 rntfnd.org/2026/10/21/new-ca… #GPS #Canada #Resilience

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. 🔗 rntfnd.org/2026/10/21/ocx-re… #PNT #GNSS #NDAA #SpaceForce

Space Force plans global deployment of up to 56 satellite-#jamming systems — a reminder that #GPS and other signals from space can be disrupted. 🔗 rntfnd.org/2026/10/20/space-… #PNT #GNSS #SpaceForce

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. 🔗 rntfnd.org/2026/10/17/prepar… #PNT #CriticalInfrastructure #GNSS

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. 🔗 rntfnd.org/2026/10/16/fortre… #GPS #CriticalInfrastructure

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. 🔗 rntfnd.org/2026/10/14/uk-gov… #PNT #Maritime #eLORAN

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? 🔗 rntfnd.org/2026/10/11/38-kil… #GPS #PNT #AviationSafety #Russia #RIN

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. 🔗 rntfnd.org/2026/10/10/gao-di… #GPS #GAO #NDAA #PNTPolicy

@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. 🔗 rntfnd.org/2026/10/09/gps-fr… #PNT #Spectrum #FCC

"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. 🔗 rntfnd.org/2026/10/08/the-ar… #PNT #Maritime #Timing #ION

Words mean things: the UK has contracted for a #ResilientPNT Standard — agreed definitions against which systems and equipment can be measured. 🔗 rntfnd.org/2026/10/05/uk-res… #PNT #Standards #GNSS #CriticalInfrastructure

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. 🔗 rntfnd.org/2026/10/04/opinio… #PNT #GNSS #Aviation @faanews

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. 🔗 rntfnd.org/2026/10/01/when-g… #GNSS #Spoofing #UAS

Maritime #jamming and #spoofing have caused ship collisions, fires, and groundings — and insurers, who can wield financial incentives, are increasingly concerned about the lack of resilient #PNT. 🔗 rntfnd.org/2026/09/30/insure… #Maritime #GNSS

Dr. Zak Kassas asks what role #LEOPNT will play in the future #PNT ecosystem if it succeeds — and why one size does not fit all. 🔗 rntfnd.org/2026/09/29/one-si… #GNSS #Jamming #Resilience

Norway shut down Loran in 2015 betting on #Galileo. Now a new FFI report warns GNSS loss could weaken its total defence, and the government is budgeting ~$10M for a national "super clock." 🔗 rntfnd.org/2026/09/24/norway… #PNT #GNSS #Russia #Norway

Current & proposed @faanews rules for beyond-visual-line-of-sight drones barely mention #PNT — yet it's what tells unmanned systems where & when they are. 🔗 rntfnd.org/2026/09/22/unmann… #GNSS #UnmannedSystems #Drones #FAA

The @uscg and @FBI boarded two US-bound ships after apparent hacks, one a very large oil carrier. Large vessels tend to have very few #Cybersecurity protections and unsophisticated navigation systems. 🔗 rntfnd.org/2026/09/21/two-us… #Maritime #PNT #CriticalInfrastructure

Switzerland is removing proven #ILS landing systems in favor of GPS-only approaches — pilots and @easa pushed back before it went further. 🔗 rntfnd.org/2026/09/17/no-tro… #GPS #GNSS #PNT #Aviation
