Method of acquiring a satellite signal and device for acquiring a satellite signal

摘要

A method and device for acquiring a satellite signal includes the step of calculating a correlation result of a reception signal from a GPS satellite and a replica code using an output value of one adder-subtractor for a combination of addition and subtraction corresponding to time-series change in code values of the replica codes from among a plurality of adder-subtractors for addition-subtraction of sampling values obtained by sampling the reception signals in a time series with different combinations of addition and subtraction, and the step of acquiring the satellite signal of the GPS satellite using the correlation result.
