This begs the question, what do you do if you're on a GPS approach
when they shut the system down?


You mean other than go missed and shoot something else? Kind of similar
to what you'd do if your GPS went South on you in the middle of an
approach?

So, you're saying there are no GPS approaches whose missed approach
procedures rely upon GPS?

No, I didn't read that anywhere in his post. I believe his intent was to
say that it's obvious that many a liberal will go nuts about how we're all
screwed now that the government has a plan to shut down GPS (which I had
always understood that this was in place anyway). If terrorists are somehow
using our own GPS system against us, then I'm all for shutting it down (or
limiting it to military use somehow).

More the reason to keep the VOR's working.

Gotta be a "liberal" to be concerned about that, huh?

Now this line of reasoning scares me. That, and that the previous
sentence will be completely misconstrued by all the red-staters.

You forget...the red-staters are the one's with the guns.....

Aren't you required to have means to execute a non-GPS approach at either
your destination or alternate to be legal?

The real impact of this sort of thing will be (1) to convince the
Europeans/Russians/Chinese to deploy their own GPS-type system (effectively
obviating the advantage of being able to shut down the US system) and (2) to
prevent use of GPS as a true sole-source navigation system.

The U.S.S.R. had one at one time. What happened to it? Couldn't afford the
upkeep?

The desire for safety stands against every great and noble enterprise.

The Soviet Union began launching satellites for GLONASS, their GPS
equivalent, back in 1982. When the country went out of business,
upkeep slowed, and the original 24+3 satellite system is down to 8,
making it essentially useless. You need multiple locks to use
GLONASS/GPS for navigation, so...

There was some discussion of a new GLONASS replacement called
GLONASS-M, but it's contingent on money which is in somewhat short
supply in Russia.

There is a new system in the works by the europeans, Galileo. It is
supposed to be independent of military control so you won't see threats
of system shutdown. I'm sure the pentagon is working out how to jam it,
etc.

Let the cat'n'mouse games continue. In previous centuries road signs
were moved around and fake maps made to confuse the enemy, I doubt that
has happened in a while. But the stakes are always getting higher, no
one died as a direct result of a sign movement (the guys with guns
lying in ambush on the other hand...)
