A global positioning system receiver and a correlating circuit thereof are disclosed. They sequentially and in parallel generate the portion of bits of the C/A code representing the satellite, sequentially and in parallel generate the portion of bits of the corrected frequency code of Doppler effect, and sequentially outputs the portion of bits of the C/A code and the corrected frequency code therefrom for multiplying the data and the IF data and for adding the products therefrom for generating the total summation value. Therefore, the correlating circuit having portable process is formed. Moreover, an external memory is used to store the sample digital data for reducing costs.
