North Korea

GPS satellite orbit, GPS clock being off or 'drifting', receiver noise, and receiving a signal at 10 degrees or less to the horizon (multipath) can cause errors. It's said that the intentional injection of errors was disabled, but that's also something that's so heavily classified that I would highly doubt that it's been disabled.

Wups. I meant magnitude of the major factors. cn

From their test done:

Civilian reaching up to 50m off, military sitting closer to 5-7m .. that's directly from nps.edu .. which is the Naval Postgraduate School, although it doesn't carry a .mil domain

Fifty meters is in the X-ring with even a small nuke! cn
 
Sorry guys you lost me in the tech talk a bit back. Is tgis all good or bad, and whos using what to do what? Little boy words please :lol:

Our GPS, even if it's completely off.. will still bbq the target as the most the bomb would miss the intended ground zero coords by is 150ft / 50m (assuming civilian GPS) or 15-21ft / 5-7m (if using military GPS) Am not sure as to N.Korea's GPS development / systems, etc.. so can not speculate or begin to guess on their accuracy assuming the tech exists at all in a semi-sane fashion.

Yes, that it is - no doubt in my mind.

Who'd'a thunk that some of today's ubiquitous, taken-for-granted tech would make easy what we spent so much money trying to do in the Titan era ... when B-52s with war loads were patrolling the high Arctic ... cn
 
And this is in peace time. In my broad and deep but unclassified knowledge there is not another gps cloud in orbit.

But, since Korea has launched satellites and China must have some orbital navigation assets. It is possible our GPS constellation would not be used. Inertial nav could be backed up by just one or two satellites.

We will turn it ofF, completely before we let anyone use it against us. And didn't de-rez the entire system during Desert Storm? Who knows what they have now? It's much better to let us think they aren't spy assets also.

And I'm quite sure specific birds within the horizon of a weapon can send false timing returns. They may be able to tight beam those returns to spoof the signals only to one weapon, area, etc. What ever they tell us the military surely has encrypted bands on their birds to not depend on the civilian sats.

However, I was reading just now that there are 31 Sats left from 59 launched over all, in the GPS and they have not launched one in a while.

It's amazing, it truly is to me.

lol! Imagine if they had GPS guidance, and we simply pulled the plug during boost ...

Yeah, poor babies. I'm not sure how sophisticated or available is old tech, black market Inertial Guidance. Believe it or not terminal reentry homing can be done with captive pigeons. You train them to recognize the target area and peck it.

Straight B.F Skinner conditioning. Pavlovian response. Good peck brings food, peck the target, peck the target. Hee hee.

When the target centers up...food! Even N.Korean bamboo rats can be taught, I imagine. It's been done.

You two just gave me a hell of an idea, I need to get my hands on a specific chipset to test it though... which will be the difficult part.
 
Am thinking Atlas booster, with heavy mods to the side-scatter beamrider, throwing in an advanced camera system and movable fins with gimbaled thrust... so it can intelligently navigate around mountains on a low altitude pass, GPS as 'general' navigation, and when it's crunch time.. it's effectively steerable with the fins and gimbaled thrust all the way until impact.
 
Ah the First Generation Tomahawk Cruise missile. Low flying, deep penetration, no recall; hellfire into the heart of the Soviet Bear. (brown) Before GPS. Would follow a terrain map with dead reckoning, time to turn points. Used a radar altimeter to follow the valleys.

Yes, but with a re-design.. so it was steerable for its final seconds in 1 piece. :D
 
Man the stuff you see. I was looking at the latest in powered exo-skeletons...but I forgot about that.

I don't normally post video. But, this is making no point. It clams to show video of a US Solider in some kind of light bending clothing.

We know that there is a lot of promising research for the Invisibility Cloak....but this is bunk, I'm sure.

So let's just say, it's still April 1, in my part of the world. If you know there is research on new materials, just go to exactly 2 minutes. A US tank trips a mine or an IDE....keep watching. Another tank drives up....watching. What the hell is that??? Pretty jaw dropping and weird. I offer it for amusement, but who knows?
