摘要：A demodulation unit for a GNSS signal processing device includes an operatorthat selects an error detecting method based on signs of early and late differentialvalues and calculates an error detection value. A code phase range where an errordetection value is not 0 is wide with a first error detecting method, and is narrow with asecond. Immediately after capturing a GNSS signal, a code phase difference between theGNSS signal and a prompt replica signal is large, and signs of the early differential valueand the late differential value are different from each other. In this case, the first methodis used. As the code phase is driven, the code phase difference between the GNSS signaland the prompt replica signal becomes smaller, and the signs of the early differentialvalue and the late differential value become the same. In this case, the second method isused.
