They don't really use GPS like you think anymore. They have realtime ground mapping with another system now. That's why GPS went into public domain. The new system can render the ground in 3d realtime and pass many other forms of information. I forget the name of this new system can somebody refresh my memory.
Wow
I knew GPS improved but was not aware of a complete redesign of this extent. This means that our missles can actually "see" and fly between bbuildings and trees.
Since it is not public domain are we the only ones with this technology?
What I want to know then AirSluf, is what's it like in the SR-71 Blackbird...which is an aircraft that was built around 1958. Did this wild stab in the dark hit anything?
Just another strange fact, military grade 741 opamps are held to a much higher tolerance than th. consumer versions. . . . The consumer versions have an open loop gain of about 200,000, but the military ones only 50,000.
And as for analog circuits, toss in some potentiometers and then you can adjust to airframe changes. I bet the SR-71 used an analog computer. . . The Apollo lander and control modules had analog computers.

I can confirm a lot of what AirSluf has said- although my experience is not from the 'using' more so than the 'designing'.
the only correction (addition?) i'd make is that the time to use varies highly. For instance, some technologies might see use within 1-2 years of being designed (i've seen this). Others could be 10-12. So the processors in some weapons we have are not as old as many might think, and some weapons being designed will be in use far sooner than 10-12 years. But then again, you gotta understand that these weapons wont be the majority.. ie they arent the kind you see the specs for on cnn.
as far as the ppc chips' use in missiles goes though, i can say that there are systems in weapons being designed that use it. I've seen 4 "altivecs" (-as the comp guys call them) in one instance. I didnt know they could be used in the way they were.. I'm not that familiar with those chips though .. so I dunno.
But the chips are very good from what I hear and they are actually needed, a lot. so dont be surprised when you hear about the processing power of these weapons.

The military ones seem to have thicker gate oxides and generally more robust transistors. Hence more durable, but less performing.
(Amps have a theoretically infinite open loop gain. Gain is the output voltage over the input voltage)
