Abstract
A reception signal integrating method includes: calculating, in receiving a satellite signal, when a reception signal of the satellite signal is time-divided at an assumed period obtained by estimating code period time of a spread code of the satellite signal, a coefficient representing a period shift between a true period and the assumed period of the spread code using first portions and second portions having an assumed period different from that of the first portions in the reception signal; and integrating the reception signal using the coefficient.
