Abstract

Modern trends of further development and improvement of aerospace systems, increasing safety requirements of space and air vehicle predetermine increasing demands for accuracy characteristics of radio measuring systems of the control parameters of motion of aircraft. Significant place in the overall structure of radioengineering safety aids of FO occupy frequency and phase radio system (RTS). In the development and practical implementation of filter of phase frequency and paths RS active selecting systems (ASS), with the scheme-frequency phase-locked loop type PAC, FL and FPL as their main element are widely used. This report give analysis of their main properties, advantages and disadvantages on such basic frequency parameter as the band capture and the variable frequency filtere signal holding, frequency and phase tracking errors and others.
