Abstract
A satellite signal receiver apparatus by which the hardware scale can be suppressed while high speed synchronization is assured. A carrier frequency component is removed from a satellite signal. Then, adding those of signals obtained after every period interval of spread spectrum codes and signals stored in a memory which have a same phase at the period intervals and writing an addition result back into the memory are repeated by a number of times corresponding to plural periods thereby to accumulate signals corresponding to sums of the signals added over the plural periods at the period intervals into the memory. Then, correlation calculation is performed between the signals for the one period of the spread spectrum codes corresponding to the plural periods and a spread spectrum code of the receiver side to detect a correlation point between the satellite signal and the receiver side spread spectrum code.
