Efficient jamming signal against civilian GPS receivers

Abstract

Civilian Global Positioning System (GPS) receivers are subjected to different types of jamming/interference impacts, which degrade its accuracy and reliability.It is well known that GPS signals are considered weak signals; thus, it can be efficiently jammed by using a GPS jammer.One of the paper goals is to increase the interference effectiveness in such a way being able to jam multiple satellites simultaneously, causing continues loss of lock for the GPS receiver tracking loop and decreasing the mitigation probability; a novel jamming signal is proposed which increases the interference influence zone and affects more than one satellite simultaneously. The proposed jamming signal has the ability to generate continuous loss of lock for the GPS receiver-tracking loop and to decrease the mitigation probability. The proposed jamming signal affects all GPS satellites with nearly small interference tolerance value and causes continuous loss of lock to the carrier-tracking loop of the GPS receiver.
