Problem statement. The use of BPSK signals with an unlimited frequency range in local navigation systems leads to a relatively high level of out-of-band radiation. To reduce the level of out-of-band radiation, the frequency band of the navigation signal is limited using a shaping filter. The disadvantage of this method of limiting the frequency band of the navigation signal is time distortion.

Purpose. Investigation of the effect of distortion of a navigation signal with a limited spectrum width on the efficiency of its processing in a delay tracking system.

Results. The dependences of the delay filtering error for navigation signals with limited and unlimited frequency bands on the interference/signal ratio are obtained.

Practical significance. The presented results can be used by specialists in the field of satellite radio navigation in the modernization of GNSS.
