PROBLEM TO BE SOLVED: To provide a satellite positioning method enabling to find a receiving position, even in case of an attenuated satellite received signal, with ultra-sensitivity and good responsiveness. SOLUTION: In this satellite positioning method, a receiver terminal receives signals from a satellite, and the receiver terminal determines a pseudo distance with the satellite from the received satellite received signals in a predetermined time T. The receiver terminal identifies the polarities of navigation data of the satellite received signals in the predetermined time T, synchronously adds the satellite received signals in the predetermined time T with identified polarities, and detects a delay value by computing the resulting synchronously added signal to determine the pseudo distance.
