Abstract:
1. A positioning system comprising: a receiving terminal for acquiring terminal positioning data from a satellite, the receiving terminal being placed in a fixed manner at a positioning target location determined by a positioning process; a reference station for acquiring reference positioning data corresponding to the terminal positioning data from a satellite; and an arithmetic processor for receiving and analyzing the terminal positioning data and the reference positioning data corresponding to the terminal positioning data, wherein the arithmetic processor includes: a storage section for storing the terminal positioning data and the reference positioning data as analysis data; and an analyzing section for analyzing the analysis data, wherein upon receiving the terminal positioning data and the reference positioning data, the arithmetic processor accumulates the received terminal positioning data and the received reference positioning data on the analysis data previously stored in the storage section, stores the accumulated data as new analysis data, analyzes the new analysis data in the analyzing section and then transmits an analysis result to the receiving terminal, and wherein the receiving terminal placed in the fixed manner at the positioning target location determined by the positioning process includes: a storage section for storing the terminal positioning data acquired from the satellite for a predetermined time; and a good-or-poor determining section that determines whether the analysis result received from the arithmetic processor is good or poor, and wherein once the terminal positioning data is stored in the storage section for the predetermined time from an acquisition start time, the receiving terminal transmits the terminal positioning data to the arithmetic processor and continues to acquire the terminal positioning data, and upon transmission of the analysis result from the arithmetic processor, the receiving terminal determines whether the transmitted analysis result is good or poor using the good-or-poor determining section, and when the transmitted analysis result is determined as poor and the terminal positioning data is stored in the storage section for the predetermined time from a last transmission of the terminal positioning data, the receiving terminal transmits the terminal positioning data to the arithmetic processor and continues to acquire the terminal positioning data, and when the transmitted analysis result is determined as good, the receiving terminal completes the positioning process of the positioning target location.
