Bush Prepares for Possible GPS Shutdown

Well, if you can't intercept incoming missiles, you've got to do
something:


President George W. Bush's drive to deploy a multibillion-dollar
shield against ballistic missiles was set back by what critics
called a stunning failure of its first full flight test in two
years. The abortive $85 million exercise raised fresh questions
about the reliability of the first elements of the plan, an heir
to former president Ronald Reagan's vision of a space-based
missile defense that critics dubbed "Star Wars." The
interceptor missile never left its silo at Kwajalein Atoll in
the central Pacific, shutting itself down automatically because
of an "anomaly" of unknown origin, the Pentagon's Missile
Defense Agency said. About 16 minutes earlier, a target missile
had been fired from Kodiak, Alaska, in what was to have been a
fly-by test chiefly designed to gather data on new hardware,
software and engagement angles, said Richard Lehner, a
spokesman. BOEING CO., the Pentagon's prime contractor on the
project, declined comment.

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.
