Future of Lockheed's cruise missile is brighter

After an uncertain two-year flight, Lockheed Martin Corp. 's advanced cruise missile has cleared a critical Pentagon hurdle that is expected to send the multibillion-dollar program into full production, ...

Questions remain about how reliable the system is -- especially its anti-jamming Global Positioning System guidance technology, said John Pike, founder of Globalsecurity.org , a defense research and consulting firm in Washington.

"That is not a value judgment; it's a matter of the facts," he said. "The GPS keeps dropping out on them, and they are puzzled by that. As far as I can tell, they are just beginning their reliability test program and there's still a long way to go."

Hey, Lockheed, you need STAP - Space Time Adaptive Processing - to reject jamming on the GPS.

If it is "just dropping out" then you need more antenna gain or less noise temperature in the receiver.

No tactical GPS receiver should be without STAP.

But, of course, true STAP is computationally too burdensome, so you need an optimal STAP algorithm for the available computational capacity.

Their future does indeed look bright. There will be more and longer wars in the future and those cruise missiles will be going all over the place. If I had some extra dough, I'd be investing in them right now. War is big business, just like prisons, and those in the war and prison businesses will just get richer. Right on Washington.

Doom and Gloom and 'Loathe-the-Military' Liberals go hand in hand.

Goods news for America is bad news for Doom and Gloom Liberals.

Oh, and maybe Lockheed's 'drop-out' problem is timing synchronization. Timing synchronization is critical to decoding the pseudorandom GPS signal, which is hard for a moving receiver, especially a fast moving receiver in a JASSM.
