Results of perspective radio navigation system (RNS)radiofront-endpassive filtering linkanalytical description development are given in article. The feature of RNS is spread-spectrum minimum shift keying signal using. The analytical description of passive filtering link is received in the form of complex coefficient of transfer, and allows to analyses frequency and dynamic characteristics of the filter. Adequacy of thepassive filtering link received description is proved by results of the modeling which has been carried out in OrCAD circuitry designsystem. Amplitude-frequency, phase-frequencycharacteristics and passive filtering link group time delay (GTD) are given in the article. Nonlinearity of frequency characteristics of radiofront-endhas impact on RNSsignal quality. The presented results will be used for an assessment of radiofront-endinfluence to theRNScharacteristicsand decision procedure to characteristics correction by means of digital methods, parametric or structural optimization.
