Analytical expressions are suggested for GNSS receiver performance such as the effective C/N0, code tracking (DLL) error and carrier phase tracking (PLL) error for a receiver affected by CW interference signals. The navigation signal model is applied to GNSS power spectral density (PSD) to interpret spectral line effects within receiver tracking low pass filter, limited by navigation data bits. A scaled envelope model is also introduced to estimate average susceptibility of signal against CW interferences. Numerical results show how the spectral lines and correlator model can affect the tracking performances, and the sensitivity of GNSS signals against the CW interferer is investigated by varying data bit duration or integration time.
