Method of increasing noise immunity during reception of signals from satellite navigational systems

Errors are reduced when tracing PRNS code delay, especially in receivers operating on signals with rather low code frequency (C/A code) under multibeam effect without deterioration or with minimum deterioration of the signal-to-noise ratio. A method of increasing noise immunity during reception of signals from satellite navigational systems and a device for realizing the same includes radio modules, an analog-to-digital converter, a digital correlation device and digital correlators. A discrimination signal is generated with a variable delay of the signal copy with respect to the exact copy. The use of the correcting sequence of gating digital signals makes it possible to eliminate the multipath effect at a delay of the reflected signal larger than 1.5 d and reduces its negative effect starting from a delay value greater than d/2. In this case, the energy losses compared with a pure mode of the narrow correlator are increased only by 1.76 dB.
