摘要： An accurate position measuring system includes a communication satellite, a position measuring satellite, a position reference station, a network management station and a position measuring device. The communication satellite performs data communication. The position measuring satellite transmits position measurement data necessary for a position measurement calculation. The position reference station receives the position measurement data from the position measuring satellite and calculates positional error information. The calculated positional error information is transmitted to a network management station. The network management station collects the positional error information transmitted from the position reference station and transmits the collected positional error information to the communication satellite. The position measuring device receives the position measurement data from the position measuring satellite and calculates its current position. The position measuring device further receives the positional error information transmitted from the network management station through the communication satellite and corrects the calculated position information by means of the received positional error information.
