METHOD OF THE GLONASS NAVIGATION SIGNALS BAND EXTENSION WITH THE MEANDER SUB-CARRIER MODULATION Russian patent published in 2018 - IPC G01S19/01 

FIELD: radar ranging and radio navigation.

SUBSTANCE: invention relates to the field of radio navigation, namely to the satellite navigation systems navigation radio signals range expansion methods, and can be used during the GLONASS system navigation equipment development intended for the navigation signals transmission with frequency and code division. GLONASS navigation signals band expansion method using the meander subcarrier modulation includes the generating a sub-carrier frequency meander waveform by the BOC signal or the Duo-BOC signal modulating at the carrier frequency, allowing to place groups of the spectrum main lobes in the allocated for GLONASS frequency bands, at that, enabling the spectrum main lobes separate simultaneous reception in two frequency bands in any combination of the L1, L2, L3 bands.

EFFECT: technical result consists in increase in the navigation signals band.
