Annotation: In this research, the authors designed and manufactured a prototype unit of multichannel receiver module system for autonomous navigation which provides the concurrent reception of Global Navigation Satellite System (GNSS) signals (GLONASS, GPS, GALILEO and COMPASS) in L1-band. The experimental tests of the basic parameters were carried out. Rationale for choosing was obtained about design features of multichannel receiver with integrated VCO circuits and single frequency conversion.
