Abstract
A LEX signal tracking method of continuously tracking a LEX signal is provided. The LEX signal broadcast from a Quasi-Zenith Satellite is demodulated. A weekend approach notification signal Sis generated based on a time within a week obtained from the demodulated LEX signal. A state of a Long code, which is generated when a code correlation processing is performed, is analyzed. If the analyzed code state is in agreement with a stored 997425th code state, a pulse signal dplus is generated. If the generation of the pulse signal dplus is immediately after the detection of the weekend approach notification signal S, the Long code is reset to an initial state.
