SAE, the world’s largest standards setting organization, recently concluded a work group meeting on standards for complementary PNT to protect critical infrastructure and automated vehicles of all kinds (air, land, sea).  The US government has twice announced that the system it will build to complement GPS is eLoran, so SAE is putting a lot of effort into standards for that technology. We understand some standards for eLoran will be completed this year. Here are some of the ones they have in progress (click item to go to the SAE page for it):

Introduction to the Operation and Use of the Transmitted Enhanced Loran (eLoran) Signal 

Specification of the Transmitted Enhanced Loran (eLoran) Signal

Loran or Enhanced Loran (e)Loran Position, Navigation, and Timing (PNT) Interface Specification for the Embedded Global Positioning System and Inertial Navigation System (EGI)

Requirements for a Terrestrial Based Position, Navigation, and Timing (PNT) System to Improve Navigation Solutions and Ensure Critical Infrastructure Security

A Guideline for Using the Transmitted Enhanced Loran (eLoran) Signal for Timing, Phase, and Frequency

Transmitted Enhanced Loran (eLoran) Signal Standard for 9th pulse modulation

Transmitted Enhanced Loran (eLoran) Signal Standard for Tri-State Pulse Position Modulation

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.
