ARCHITECTURE OF SIGNAL PROCESSING IN SATELLITE NAVIGATION SYSTEM RECEIVER Russian patent published in 2011 - IPC G01S5/14 

FIELD: physics.

SUBSTANCE: proposed device comprises universal radio frequency receiver. Said receiver receives signal comprises, at least, one signal with spectrum spacing from first satellite. Receiver has, at least, first channel incorporating, at least, two sub channel circuits. Each sub channel circuit comprises, at least, first signal generator and first mixer designed to receive appropriate frequency range in, at least, one signal with spectrum spacing from first satellite. First signal generator generates appropriate first signal with appropriate first carrier frequency, to convert, at least a portion of signal with reduction of frequency to intermediate frequency, common for both said two sub channel circuits, using first mixer.

EFFECT: development of all-purpose radio frequency signal receiver for signals of carrier frequencies in global satellite navigation system.
