Congress held a nearly 3.5-hour hearing on U.S. #PNT policy — nearly every panel member challenged NextNav's #FCC petition, and lawmakers raised privacy and tracking concerns about future positioning systems.

#LEO #PNT offers greater performance and resilience than existing #GNSS — commercial companies are building it now, the EU may offer it free, and the U.S. government is weighing whether to buy in.

NAB has spun off Merkhet Solutions to deploy BPS — a patented terrestrial #GPS-independent timing and positioning system built on existing U.S. broadcast infrastructure.

As #GPS jamming grows, magnetometry is emerging as a standalone alternative for GNSS-denied environments — but can't replace the #PNT timing function critical infrastructure depends on.

Nine years after Munich first called for a #GNSS backup, the 2026 summit no longer debated whether — only how. But for the U.S. and most major economies, resilient #PNT remains more aspiration than action.

The FY27 NDAA markup would replace DoD's #PNT oversight council with a single official — but Congress has tried to fix #GPS governance before, and legislation alone hasn't been enough.

More than 85% of UK imports and exports by volume move by ship — and Rear Admiral Iain Lower warns the Dover Strait chokepoint now demands resilient #navigation as economic and national necessity, not luxury.

SWF 2026 Counterspace Report: 6,904 debris pieces from US, #Russia, #China & India ASAT tests — 2,773 still on orbit. #GNSS resilience can't be planned apart from this.

The Telegraph: #Russia is spoofing Ukrainian drones at #NATO targets in Lithuania & Latvia. GNSS interference in the Baltic has crossed from chronic nuisance to cross-border kinetic effect.

Canada ends CHU shortwave #time on June 22 — retiring a sub-ms UTC(NRC) reference. Replacements: web/NTP (~10–100 ms) and a talking clock (~1 s). A real loss for #PNT resilience.

Companies are marketing tools to governments that can geolocate #Starlink terminals — a reminder that two-way satellite services create tracking exposure that one-way #GNSS broadcasts do not.

Bee-Nav — a honeybee-inspired drone navigation system — runs on just 42 KB of memory, hinting at ultra-low-SWaP autonomous #PNT that could complement #GNSS where signals are denied or unreliable.
