FIELD: radio engineering.
SUBSTANCE: method to generate a signal of modulation of a subcarrier for modulation of a distance measuring code of a navigation signal comprises a stage of multiplexing in the time area of parts of the first and second subcarriers of a binary displaced carrier (BDC) to produce the specified signal of subcarrier modulation. In the other version of invention realisation the method includes a stage of multiplexing of parts of the first and second subcarriers of BDC thus spectral peaks position is influenced, and the peaks are related to the specified first and second BDC subcarriers within the spectrum of a signal of subcarrier modulation.
EFFECT: provision of electromagnet compatibility.
