This article on Space.com talks about how satellites play a crucial role in ground battles. Also, this link on CNN.com shows that about all of the weapons the military are using that nearly all are made smart by GPS navigation systems. Isn't it amazing that all of these UAV robotic weapons are using GPS? And, isn't it amazing that the technology has even come this far? Years ago, did you ever think that we'd someday be using GPS guided weapons? Even the once dump bombs that drop from planes now have smart GPS guidance systems to help them locate their targets: see the JDAM bombs. It's like just about all of the weapons now they just give them a task and then they carry that task out autonomously. I guess this is the unheralded beginning of robotic warfare?
