<p><P>PROBLEM TO BE SOLVED: To provide a satellite position system using reference receiver, more specifically a network of reference receiver for satellite positioning system. <P>SOLUTION: Satellite ephermeris data received from SPS satellites from which a particular SPS reference receiver can be seen. Multiple digital processing systems are connected to a telecommunication network for receiving satellite ephermeris data transmitted via the telecommunication network. The digital processing system receives pseudorange from SPS mobile receivers, and computes position information of the SPS mobile receivers from display of the satellite ephermeris data and from the satellite ephermeris data received from the telecommunication network. The digital processing system receives correction values for pseudorange from the telecommunication network, and uses these correction values to correct pseudorange data so as to carry out display of pseudorange data. In one embodiment of this example of the present invention, mobile SPS receivers are connected to communicate with each other. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
