I've open sourced my location

The author has publicly published his location. This has little to do with the regular use of the open source term.
but You can suggest a good word :) I won't mind to change it.
What do you understand when I say "open source"?
How do they do it? I was under impression that GPS (or GLONASS/Galileo) satellites are basically just flying atomic clocks, and even Iridium (which is probably what the author means by "72 satellites") can't track people.
There were already so many incidents happened and came in picture on GPS tracking misused. You can google it. I personally believe they can track you when they want to track you.
