Problem statement. Necessity of simultaneous forming and emitting several interfering signals with different parameters on one or two frequencies in different sub-bands in case of jamming of navigation user equipment operating with signals of one global navigation satellite system requires substantial frequency and spectrum resource of jamming station in their technical implementation. 

Purpose. Enhancing the effectiveness of frequency band-stop method of ECM of global navigation satellite systems navigation user equipment due to concentration of interfering signal spectral density within the working area of suppressed frequency band through the use of interfering signals with additional meander modulation on subcarrier frequences (BOC signals).  

Results. The methodology developed allows to calculate rational with maximum achievable situation effectiveness parameters of interfering signals with additional meander modulation on subcarrier frequencies. Application of of interfering signals with additional meander modulation on subcarrier frequencies provides the increase of interfering signal spectral density within   the working area of suppressed frequency band by 31 per cent. 

Practical relevance. The results may be used to support the requirements for types and parameters of interfering signals of jamming equipment of global navigation satellite systems navigation user equipment.
