Blog Editor’s Note: A good overview article.

One note, though. The $1.3B loss per day shown for the U.S. should we be without GPS comes from an RTI study done for the National Institute of Standards and Technology. That seems like a big loss that we should act to prevent (and we should).

But U.S. GPD is about $63B/day. So that means the RTI study says that if we lose GPS, our economy will only suffer by 2%.

Does that amount seem way low to you?  It does to us.


Strengthening PNT to Avert Economic Setbacks

Resilient PNT is neither a particular technology nor a service; it is actually a combination of many things, depending on the scale and scope of applications and systems.

The world we live in today is critically dependent on Positioning, Navigation and Timing (PNT) services provided by the Global Navigation Satellite System (GNSS). Of course, the Global Positioning System (GPS), developed by the US, is the most widely used technology. Apart from commercial operations, we heavily rely on PNT services for national security and critical infrastructure applications. From squadron coordinates for military missions, precise location data for search and rescue operations, scientific pursuits for environmental and disaster monitoring to increasing efficiency and productivity in areas like construction, oil and gas, and mining, everything runs on PNT. Perhaps that is why the value of these services is growing by the day. However, the heightened reliance on these services can lead to socio-economic losses as these systems are prone to disruptions, interruptions, and manipulations.
