PROBLEM TO BE SOLVED: To provide a GPS receiver for accumulating and adding a C/A code by correcting polarity reversion of the C/A code, without using navigation message acquired from the outside, when performing coherent processing performed prior to correlation processing. SOLUTION: The GPS receiver for performing correlation processing by using a replica of the C/A code generated in an inside, after performing accumulation processing of a GPS signal received from a GPS satellite adds a plurality of addition signals generated in the inside by predicting modulation of the GPS signal by the navigation message to the received GPS signal in accumulation processing, and performs accumulation and addition, as a result of the addition.
