Russians are going to spoof GPS

Daily Mail: Russia has claimed to have built a revolutionary new weapon system that can render enemy satellites and weapons useless.

Its Russian makers say it is a 'fundamentally new electronic warfare system' which can be mounted on ground-based as well as air- and sea-borne carriers.

However, it has refused to reveal how the system works.

And the guided missiles will have inertial guidance back up. The Russian spoof is only good for a few miles I am sure, they cannot get the angle needed to completely suppress GSP.
