Signs of a Covert War Between the U.S. and Iran
Dec. 17, 2011 — -- There are unavoidable signs that the U.S. and Iran are engaged in significant covert actions against each other, including cyber war. Among the alleged covert activities that have been reported are:
It is against that backdrop of rumored covert action that Iran now claims to have captured a U.S. stealth drone, the RQ-170 Sentinel. Pentagon spokesmen quickly denied that Iran had outwitted the U.S., claiming that Iran had "lucked out" when U.S. pilots "lost control" of the RQ-170 and it just crashed in Iran. But is there a chance that Iran is right; how could Iran have done it? It might have happened something like this:
Iran could easily have learned where the U.S. RQ-170s are based in Afghanistan and might even have been able to notice when they take off and head toward Iran. They might well have guessed, correctly, that the RQ-170 was headed for an Iranian nuclear facility.
Iran could have stationed its newly acquired Russian Electronic Warfare (EW) truck mounted system, known as Avtobaza, near the nuclear facility. The Russian export is designed to manipulate the guidance and communications system of U.S. weapons. Using that system, Iran might have jammed the command-control link between the U.S. drone and the commercial satellite the drone uses to link back to its pilot.
When the drone can't talk to its pilot, after a while, it aborts its mission and goes home. To find its way home, the drone uses signals from the Global Positioning System (GPS) satellites. Unfortunately, the signal strength of the GPS satellites is relatively weak and a strong signal from something like the Russian EW systems can overpower it. This technique has been frequently demonstrated and allows something like the Russian trucks to "spoof" the GPS signal, pretending to be the satellite and providing false data to GPS receivers.
