No, the GPS "system" gives you coordinates. It has nothing to do with a map and the map is entirely optional.

For navigational purposes, it's a necessary option, but it's not a component of the system. The system is the satellite constellation, radio protocols, and associated algorithms. The system's output is your coordinate information - which as I said on it's own means nothing. You need a map to coordinate with, or another set of coordinates to do relational comparisons.

However, military aircraft have all sorts of other sensors and are generally not worn on a person's wrist. They also sit on the runway for 15 minutes spinning up gyros and aligning said INS systems... and they still have drift and need external correction from GPS systems or the like during flight.

If I dump you in an arbitrary spot with just a GPS, you'll be equally screwed. You need a map to correlate the GPS' output with, to have any use of it.

Indeed all a GPS does is give you some numbers and the time.

You need a map marked with the correct coordinate system to give any real meaning to the numbers.

It's a little hard to circumnavigate most towns without some rather serious tunneling equipment...

That would be difficult, what with the light-years of delay skewing apparent positions...

You can (fairly accurately) determine the time from sun/moon azimuth and the calendar.

Hell, the Vikings had sun stones to help them do it through the clouds!

Good would be using appropriate charges. Copyright infringement? Really? How is that even remotely appropriate?

No, but I fail to see how bypassing Warden or whatever it is to do DLL injection could possibly be construed as copyright anything.

Blue is pretty vague, yes - but it does define a perceived color. This suggests a particular peak of spectrum. "Wet" actually means something very specific.

It is when said policy is so painfully ridiculous.

Go ahead. Let's see you move a hot reactor, safely, any appreciable distance - along with any other auxiliary equipment required to keep it safe and non-melty.

Because they weren't already getting worse than that doing routine searches/bangups?

You need context for that.

Sure, it's safer without an x-ray cathode. That's some high-voltage stuff.

Indeed. You have people stabbing each other with sharpened toothbrushes... some proper form or search is necessary and metal-detection is not enough.
