A mathematical model of probability definition of the navigation signal phase-lock-loop system tracking breakdown during the allowed time under the conditions of the signal-like jamming is given. The results of signal-like jamming effectiveness evaluation conditionally its parameters as applied to GLONASS users’ equipment phase-lock-loop system using the civil signal are presented. The authors prove that the phase-lock-loop noise immunity effected by signal-like jamming decreases from 1 to 3 dB in comparison to the AWGN. The complexification of the phase-lock-loop with inertial navigation systems allows its 5…6 dB noise immunity increase under the conditions of signal-like jamming.
