An Inherent Limitative Parameter in Spoofing GNSS-Based Navigation Clients

Deception of navigational subsystems of a client, ranging from a hunting GPS receiver to the military-class GNSS receiver onboard of a Cruise Missile, is one of the probable electronic attacks. One of the simplest and practical way too deceive these receivers is to re-broadcast the delayed navigational signals. The authors were studied the feasibility of this method in the “Best” attainable conditions while the generality of study retained. The results from introduced geometrical and mathematical models were used to define the minimum and maximum operational range of Repeater Deception System parametrically. Then the parameters were substituted by information of various GNSS constellations. Investigation of reliability of selected EW scenario concluded the article.
