Abstract(in English) The three dimensional position of the GPS receiver is deduced by the iterative calculation with the pseudo ranges from more than 4 satellites. They are measured by the arrival times of C/A code assigned to each satellite. The pseudo range, that includes several errors, is corrected by the navigation message. The clock error of the receiver is deduced as the fourth solution of the positioning calculation. We developed a program which deduces the close positions to those obtained by the RT-2 receiver by using the raw data and the weighting coefficient produced by the RT-2 receiver.
