摘要

A demodulation unit (13) corresponding to a GNSS signal processing device includes an operator (33). The operator (33) uses a first error detecting method when one of a first selection criterion in which an early late differential value ”CV EL is higher than a first threshold C1 (positive value) and an early differential value ”CV E is lower than a third threshold C3 (negative value), and a second selection criterion in which the early late differential value ”CV EL is lower than a second threshold C2 (negative value) and a late differential value ”CV L is lower than a fourth threshold C4 (negative value) is satisfied, and the operator (33) uses a second error detecting method when neither criterion is satisfied. A code phase range where an error detection value is not 0 is wide with the first error detecting method, and the code phase range where the error detection value is not 0 is narrow with the second error detecting method.
