Signal tracking method of global navigation satellite system signal tracking apparatus and satellite signal receiver having the same

摘要

Disclosed are a signal tracking method of a satellite navigation system, a signal tracking device, and a satellite signal receiver including the same. In a signal tracking method of a satellite navigation system according to an embodiment of the present invention, generating a duplicate code including an E code, a P code, an L code, a first code and a second code, a received signal and the duplicate codes Calculating a plurality of correlation values for each, determining slopes of a plurality of slopes derived from correlation points corresponding to the duplicated codes, and time delay by a multipath signal component according to the determination result. Characterized in that it comprises a step of detecting.
