This protocol is apart of the GPS constellation put up by NATO countries. During times of aerial warfare the GPS system is designed to restrict access to non IFF (Identify: Friend/Foe) transponder equipped aircraft.
The tech is like this to deny foreign air forces from utilizing GPS in USA +NATO air spaces.
The company that maintains the majority of GPS in space is called Navstar. Great article from ScientificAmerican about this system from 2016.
Its funny cause after I posted this I felt kinda of stupid, I actually do not believe their is ANY satellites at all because I think space is fake. Did you know that there are undersea cables for communication and they handle 99% of ALL communication? There are many issues about satellites that nobody questions, such as how do they reposition themselves, do they have UNLIMITED FUEL? Do they EVER break down, why does nobody ever go up and repair them, how do satellites withstand the temperature extremes for 10 years plus.... Just more questions and really no good answers. Thats our world, a flat earth filled with liars. Scientific American is 100% .gov controlled just as MSM. Peace.
Be honest, how much did you smoke when you wrote this?
Lol. This is what this guy believes in. You've got to read a few of his blog posts in order to understand. I personally don't agree but also not judge. Nevertheless, for a 'conspiracy man' he's got quite a healthy attitude and open mind.
