Abstract

The invention provides a signal tracking method of a global navigation satellite system, a signal tracking apparatus and a satellite signal reciever having the same. The method comprises the steps: generating duplication codes including an E code, a P code, an L code, a first code, and a second code; calculating the correlation value of the received satellite signal and the duplication codes; identifying the gradients of a plurality of slopes derived from correlated points respectively corresponding to the duplication codes; and detecting the time delay caused by multipath signal components according to the identification results.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2012-0144801 filed on December 12, 2012, the subject matter of which is hereby incorporated by reference. technical field [0002] The inventive concept relates to signal processing methods, and more particularly, to methods and apparatuses for tracking signals of a Global Navigation Satellite System (GNSS). The inventive concept also relates to a satellite signal receiver comprising such a device and / or using such a method. Background technique [0003] GNSS is essentially a group of systems that collectively are capable of locating the location of a target object and then using an array of satellites to provide location information about that target object to ground receiving devices. [0004] GNSS includes the Global Positioning System (GPS) operated by the United States, the Global Navigation Satellite System (GLONASS) operated by Russia, and the Galileo positioning system operated by the Euro...
