ABSTRACT:
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 multiplications therefrom for generating the total addition values.
