PROBLEM TO BE SOLVED: To provide an appropriate received signal integrating method in consideration of periodic deviation. SOLUTION: A received signal of GPS satellite signal is sampled for each one clock as sampling time interval to acquire a plurality pieces of sampling data. Then, using sampling data sets with different code periods when the received signal is time-divided by an assumed period of CA code as diffusion sign of the GPS satellite signal, a periodic deviation coefficient representing a periodic deviation between a true period of CA code and the assumed period is calculated for each code period. Then the received signals are integrated using the periodic deviation coefficient. COPYRIGHT: (C)2011,JPO&INPIT |
