Abstract:
A multipath signal evaluation method includes, carrying out a correlation calculation on a received signal from a positioning satellite to obtain a peak correlation value, and determining reliability for a received multipath signal by using the peak correlation value and a correlation value at a phase delayed from a peak phase in which the peak correlation is obtained.
