FIELD: navigation equipment.
SUBSTANCE: invention can be used in GLONASS satellite system. For this purpose, measurements of signal power are performed simultaneously in three bands of different widths with centers at navigation signal carrier frequency, as a result of analysis of ratios of these band-pass power the action of noise is determined.
EFFECT: technical result consists in accounting for the effect of narrow-band and pulse interference when measuring navigation signals of navigation spacecraft of GLONASS global navigation satellite system in subbands L1, L2 and L3.
