In our next episode of Militant dictator How-to, we'll show you how to
upgrade an antique scud missile to with a guidance system capable of 3-meter
accuracy for less than $500.00 per unit.. Stay tuned!

Somehow, I find it difficult to believe I'm dignifying this with a
response (much less a public one), but here goes:
Every commercial GPS unit that I have ever seen has a speed which, if
exceeded, will cause the unit to shut down (usually until
power-cycled). It varies from unit to unit, but in every observed
case was substantially (several times) less than the speed of such
weaponry in flight. Commercial units also have altitude limits, with
the same consequences for exceeding them. Integrating an OEM GPS
module with existing avionics systems' targeting mechanism so it can
actually cause the missile to adjust its course is left as an exercise
to the local defense systems integrator.

I know my Garmin 195 functions in real life up to about 462 knotts. I
don't know what it's shutdown point for real life is, as I haven't ever
been able to deploy it in an environment going faster than that.
I also know that in simulator mode, it is good to about 1000 knotts.
If I remember correctly, the SCUD is subsonic. As such, I believe the
Garmin would handle it.

i suspect the person wanting to use gps/sa for circuit timing was presuming
their pop would not be moving very fast. if it was to move fast, i suspect
they would have problems more severe than timing.

Garmin would handle it.
given a burn time of 60-80 seconds and a range of 300-700km I'd expect
scuds to be considerably faster than subsonic.
the federation of american scientists has far more information about about
weapons of mass destruction than you probably want to know.

Hmmm...don't know...if we're talking about survivable networks, maybe an airborne POP would be one direction.
The buffers on the fiber links, however, would REALLY need to be elastic.

There's also acceleration/decceleration effects: in a missile
that goes from zero to 'sweet mother of Abraham Lincoln!!!' in
less than the time it takes to send a content-free post to NANOG,
a commercial (off-the-shelf) GPS won't last til the projectile
reaches max V.

After having about 39 pass over my head 10 years ago, I can attest that they are definitely faster than subsonic
