Abstract

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.

Highlights

Spoofing, the art of embedment or even substitution of acceptable but wrong information in place of the original one, is one of the key techniques which was and is used to deceive the receivers’ processing infrastructures including human minds and electrical processing systems
Which hRDS is the altitude of RDS over the spotted point and the hPlatform is the nominal altitude of flying platform which is equipped with suggested GNSS receiver, both in meters
To investigate the effect of minimum operational range of RDS on efficacy of its electronic warfare operation against the described GNSS receiver, three different issues should be taken into account

Summary

Introduction

The art of embedment or even substitution of acceptable but wrong information in place of the original one, is one of the key techniques which was and is used to deceive the receivers’ processing infrastructures including human minds and electrical processing systems. By advent of GNSS2 and penetration of its application in commercial, military and many aspect of everyone’s daily life, the threat of navigational spoofing is becoming an important and worrying issue[6] The importance of this menace is mostly because of any interfere in authenticity of satellite-based navigation systems could disrupt the transportation system [7, 8], disarrange remote sensing infrastructures and corrupt the accuracy of military instrumentations [8]. Any of these can threat local or domestic security of a country
