Impact of Jamming Attack on Galileo Receivers

Impact of Jamming Attack on Galileo Receivers

This paper surveys the impact of different jammers on the Galileo receivers in the L1 band. Specifically, we examined the relationship of the sweep-rate of chirp-style jammers with the detection probability when ac-quiring a Galileo signal. The simulation results show that the relationship between the sweep-rate of the chirp jammers and the resulting impaction of the acquisition process is a non-linear function. With the of 45 dB-Hz, the probability of successful acquisition is less than 95% when the sweep rate of the chirp jammer is about 1 GHz/sec and the jamming-to-signal ratio (JSR) is above 21 dB; on the other hand, when the jammer type is the continuous-wave interference, the Galileo receivers can tolerate the JSR of 25 dB.
