US Army – “eLoran is a Pseudolite”

The US Army published another Request for Information (RFI) for Assured-PNT Monday.

One of its interesting features is that it describes eLoran as a pseudo-satellite or “pseudolite.” Pseudolites are ground-based transmitters that provide the same information and services as satellites, most often GPS satellites.

Many people argue against pseudolites that broadcast in the GPS band because of the possibility of interference with satellite signals. Of course, that is not a problem with eLoran because it is at the other end of the frequency spectrum.

We have always thought that eLoran transmitters should be considered GPS pseudolites.

And we are very glad to be on the same side as the United States Army!

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.
