What’s new: Concern and press coverage about GNSS interference in the Persian Gulf and Strait of Hormuz continues to ramp up.

Why it’s important: Electronic and kinetic attacks, mostly oil, have brought shipping to a near halt and are beginning to impact the world economy.

What else to know:

  • We have seen a report in Al Jazeera that Iran is using an ‘unjammable” version of Bei Dou to direct its missiles and drones. We are looking into that. More info to follow.
  • There is evidence Iran built its own Loran/eLoran system years ago. Also, the Saudi eLoran system appears to be usable in the gulf and strait.

Here are some of the reports:

What Can YOU Do? How Can YOU Help?

PNT is the quiet backbone of everything but too many leaders still don’t see the risk.

But you do. You understand the systems, the dependencies, the failure chains. That insight is rare — and it’s exactly what your country needs right now. Contact your government leaders and industry decision-makers and tell them resilient PNT isn’t a feature — it’s the foundation everything else depends on.
