Calculation methods of noise immunity of the receivers under the mutual effect of tracking systems and complex tracking systems

[摘要] The article discusses the methods for improving the reliability and validity of the GLOSNASS signal. These methods reveal the principles of improving the signal reliability and validity by reducing the noise level from the received signal. The main attention is paid to the calculation of the noise immunity of the receivers under the mutual effect of tracking systems and complex tracking systems. The article deals with the noise immunity of coherent and noncoherent receivers, the noise immunity of the complex tracking systems.
