The present invention relates to a navigation signal tracking device capable of tracking a navigation signal. According to an embodiment of the present invention, the navigation signal tracking device includes: a reception device for receiving a navigation signal received through a multi-path; a discriminator for generating a reference signal and generating a discriminator signal by multiplying and integrating the generated reference signal by the navigation signal; and a tracking loop for tracking the navigation signal based on the discriminator signal. The discriminator includes: an asymmetric reference code generation module for generating an asymmetric reference code in the shape asymmetric with respect to an origin; and a delay reference code generation module for generating a delayed reference code which is delayed by a certain chip from the asymmetric reference code. The reference signal is generated by combining the asymmetric code with the delayed reference code. |
