What’s new: An article about DOD non-space PNT efforts.

Why it’s important: DOD has long led the way in many technologies. They certainly did with PNT by creating GPS.

What else to know: The article is about quantum projects for time and advanced inertial navigation.

  • Quantum is developing well. The article mentions some of the challenges to making it operational and widely adopted.
  • Quantum will undoubtedly be part of the solution architecture at some point.
  • Wide adoption of quantum will depend on much, much lower SWaP-C and overcoming concerns about how well timing sensors sync with each other.
  • As is the case with all PNT technologies, quantum will be part of the solution, but there is no silver bullet.

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.
