The claim that GPS works everywhere belongs to you
Nope.
In this thread I have been discussing the impossibility of faking the current system.
I was not discussing if it works in particular locations.
The first person to bring up claims of GPS working in the ocean or not working in the ocean was you.
As such it is entirely our claim.
So until you prove that GPS does not work in the ocean (or other places), it just remains your baseless claim, and I do not need to admit anything regarding it (other than it being your baseless claim).
And no, you complaining about people not proving you wrong is not proof that you are correct.
Nor is you claiming that it isn't a claim.
Nor is you claiming it.
So either prove that GPS doesn't work in the ocean, or drop the subject as without that proof (which doesn't exist) it cannot be used as any part of a rational against GPS.
If you would like to try addressing the topic, then explain how you can fake a satellite based system using ground based transmitters, proving accuracy to within 3 m, without an absolutely insane number of large, highly directional transmitters.
I will not be responding to any further spam with your baseless claims regarding GPS not working in oceans.
If you want me to respond to such claims any more (at least in this thread) make sure you include proof that it doesn't work in oceans, not just more baseless claims and dodging of the burden of proof.
