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. |
