This probably could have simply been posted to one of the several existing threads about it, but thanks for the recent update!

 

(here are two of the previous discussions for anybody that wants to catch up)

I thought this had been debunked a while back.,..

[+spyder8]

I did a search on the forum for "LightSquared" and nothing popped up,

so I posted the recent update vs adding to an existing thread..

 

tnx for the links to the other two threads on the subject.

That's exactly what I did a search for. Odd.

 

I only searched this forum. I think there may be one or two more in other forums.

[+spyder8]

wow - interesting on the search results....

I see what happened; I only searched for the beginning letters... "lightsq"

thinking that would match "lightsquared" - but it resulted in nothing found.

 

However, using the full text of "lightsquared" yields 13 threads..

So - sorry, my error - will try and do better next time in the pre-searches for finding existing threads.

[+Ambient_Skater]

These topics are made so often we're going to have to factor them into the forum schedule soon.

 

The government regulates the radio spectrum and since the US military depends on GPS it's unlikely they'd approve any sort of service that would interfere with it.

[+A & J Tooling]

It ain't just the military anymore. You don't realize the amount of problems that would happen if you jammed the gps freqs. airports, banks, police, fire/rescue, most major transportation companies, etc would suffer.

This seems to be the primary one.

Not to mention farmers.

and fishermen.

And the guys who do this:

(Yeah, I know, they're a subset of "farmers.")

[+Walts Hunting]

there are almost 50 pages of this discussion already. Maybe they could be merged. Not really news here.
