METHOD FOR FORMING GLONASS GROUP NAVIGATION SIGNAL Russian patent published in 2018 - IPC G01S19/01 H04B7/05 

FIELD: radar and radio navigation.

SUBSTANCE: invention relates to systems for generating a signal of the satellite radio navigation system GLONASS, namely, to the transmission control and correction means. Method of forming a GLONASS group navigation signal involves the generation of navigation signals with code and frequency separation in the L1, L2 bands and a code separation signal L3, their amplification and radiation through one antenna in which the signals in the L1, L2 bands with code and frequency separation are summed at the input of the power amplifier, thereby generating a sum signal having an amplitude modulation, then the group signal is synthesized by the method of optimal alignment, for this purpose all signals are represented in a complex form, then the signal is transformed into an equalizer that excludes amplitude modulation and based on the transformation of the complex signal in accordance with the definition of the function sign: , then the converter transfers the group signal to the carrier frequency.

EFFECT: technical result is the reduction of errors in signal formation by digital generation of group navigation radio signals of the L1, L2 bands, which are emitted by one antenna.
