Abstract

In a positioning system, an arithmetic processor analyzes positioning data acquired by a receiving terminal and determines a positioning target location. Upon reception of positioning data, the arithmetic processor accumulates the positioning data on analysis data stored in a storage section prior to the reception, stores an accumulated data as new analysis data, and transmits an analysis result to the receiving terminal. The receiving terminal transmits positioning data, acquired for a predetermined time, to the arithmetic processor and continues to acquire positioning data. Upon reception of the analysis result, the receiving terminal determines whether the analysis result is good or poor. When the analysis result is poor and the positioning data is stored for the predetermined time from a last transmission of the positioning data, the receiving terminal transmits the positioning data to the arithmetic processor and continues to acquire positioning data. If the analysis result is good, the receiving terminal completes positioning of the positioning target location.
