The most surprising thing to me, as I was reporting this story, was the crucial role of the T in PNT. People think about GPS as a way to get around , but timing, not positioning, might be the most critical service GPS provides to the US and broader global economy. There's two reasons:
- Timing is fundamental. Computer networks, financial markets and electric power grids all need precise timing. GPS provides that for free through low-cost equipment. But what if it went away, even briefly?
- Timing is poorly understood. It's pretty easy to know how accurate your location service has to be. Timing is different and many enterprises don't understand their timing requirement because they've never had to think about it.
Anyway, I hope you find the story interesting…

some enterprises are ***told*** to think about it.
