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:
