Title:

衛星信号捕捉方法及び衛星信号受信装置

Document Type and Number:

Japanese Patent JP4911220

Kind Code:

B2

Abstract:

Methods and apparatuses for acquiring a satellite signal includes generating a differential code using first, second and third segments of a satellite signal received from a positioning satellite, obtaining a correlation value by performing a correlation using the differential code and a replica of the spreading code, and acquiring the satellite signal using the correlation value. The differential code is generated by performing a differential operation on a spreading code from the positioning satellite.
