Iso-Doppler lines corrected for the rotation of the earth are obtained by finding the positional and speed data 2 of the satellite front the already known orbit of the satellite and inputting the data to the process 3 and the iso-Doppler lines are drawn on the ground surface. When the frequency bias correction is appropriate, the iso-Doppler lines corrected for the rotation of the earth intersect each other at one point. Therefore, whether or not the frequency bias correction is appropriate is evaluated by calculating the intersection and front the variation of the point.  When the variation falls within a small range, the point is outputted as the latitude and longitude data 6 of the transmission source.
