This has to be propaganda designed for domestic consumption, because there is no way this would be effective. You know how cell towers are on the ground, and missiles are in the air? Yeah, sky facing directional antennas in the hundreds of cruise missiles would defeat a 250,000 tower project. I'd be surprised if the functionality wasn't already built into the weapon systems - the handheld GPS unit I was issued in 2006 had the ability to detect jamming and selectively ignore the direction of the source.
