N2 - To explore the effect of narrowband interference suppression on carrier phase measurement zero value for satellite navigation system, this article establishes the equivalent filter model for classic NBIsuppression algorithm, and presents a study in order to analyze the effect of NBIsuppression on Carrier Phase bias.Then, the articlebuilds an analysis model of carrier phase zero value in the introduction of the NBIsuppression, works out the relationship between the carrier phase zero value bias and equivalent filter, and shows a condition for the unbiasedness of carrier phase measurement zero value. It is shown that linear phase filter has no effect on carrier phase zero value. Nonlinear phase filter has an effect on carrier phase zero value, which is directly related to the filter weights. Based on the Monte Carlosimulation, thebiasvalue of carrier phase measurement zero value, which is simulated in the different parameter of the narrowband interference by using classic narrowband interference suppression algorithms, is obtained.
