PROBLEM TO BE SOLVED: To provide a satellite positioning method of very high precision, capable of finding own position with ultra-high sensitivity and superior responsivity, even in an attenuated satellite receiving signal, and capable of calculating the own position based on the accurate position of a satellite. SOLUTION: In the satellite positioning method, a receiver terminal 11 for receiving a signal from the satellite S and communicating information with an external base station 1, calculates the own position. A navigation data of the satellite receiving signal, received from the satellite S by the receiver terminal 11, is compared with an external navigation data received from the external base station 1 by the receiver terminal 11, and the delay time of the external navigation data is calculated. The satellite position, when the receiver terminal 11 processes the satellite receiving signal, is estimated based on the delay time. A pseudo-distance is determined based on the estimated satellite position and the own position is calculated. COPYRIGHT: (C)2008,JPO&INPIT |
