I recently appeared on The Space Shot podcast discussing my book “GPS Declassified”.

Tell us more.....

Cool! I have bookmarked this for listening when time frees up.

Thank you!

I started researching my book in 2005. My father, Roger Easton, is one of three people generally credited with inventing GPS. In 2016, my co-author and I were invited to speak at Air Force Space Command. Gen Hyten , then the commander of AFSC, introduced out talk. there are more details at www.gpsdeclassified.com

I don't know about anyone else but I find GPS to be one of the most amazing bits of technology imaginable. My car has built in GPS and there's a setting where I can see the exact location of my car..spelled out, E.g, "2700 Main Street,Anytown,NY"

Just the other day I crossed the Massachusetts/Connecticut border and *exactly* at the border my display changed from "MA" to "CT".

It knew *exactly* where I was.

Got Spirent?

Wow...so you are an “expert” on GPS? Cool! I’ve read that the military version of GPS (I know it’s controlled by the Air Force) can track someone to the inch rather than to the few yards (or more) in the civilian version. Is this true?

[21twelve]

Surveyors use GPS to measure to way less than an inch. Of course they have a receiver at the location. And a fairly large receiver (4-inch diameter) that has to have a good view of the sky. So not something you can hide on a car.

I’m guessing ones the government can hide on a car are still good to within the blast radius of a rocket.

[MrEdd]

Cool.
I worked with the Bell/Hughes Position Location Reporting System in the early eighties at Lejiune.

We know.....

We've been tracking you....

[caver]

I’ll check it out.

[G Larry]

Toured the Lockheed GPS III facility while working other project here in Denver before retiring several years ago.

Very impressive.

[Richard from IL]

You’d generally need to use augmentation to reach accuracy to an inch or less. https://www.gps.gov/systems/gps/performance/accuracy/

When I worked in Chicago and I heard police sirens, I’d joke that they’ve found the one conservative in the city (me).

[P.O.E.]

Wonder if they still teach how to use these in schools:

[Richard from IL]

We got a tour of 2SOPS, where they control GPS, when we spoke at AFSC. The people were very impressive. http://www.gpsdeclassified.com/easton-and-frazier-speak-at-peterson-afb/ We’ve also been on C-SPAN. https://www.c-span.org/video/?427553-2/global-positioning-system-history

I/we use GPS for locating caves out in the woods. I also use them for navigating through the woods. Previously, back in pre-GPS days, we located caves by using topo maps, the 7.5 minute versions with 10 foot contour intervals. The problem with them is that a location could be a quarter to half a mile off due to person trying to put a dot on the map.

Very interesting.....

I interviewed for a job once where they showed me the GPS track of a missile test. The missile had a high speed D-GPS chip installed which broadcast position every 3 feet........ in flight. 500 mph, every 3 feet.
