4. Enter or list select the known coordinates corresponding to the measurement point at the known coordinates.
Click [Correct].

5. If the correction is successful, the corresponding measurement coordinates in the point data are modified to
the corrected coordinates. Note that if the difference between the known point coordinates and the actual
observed value is more than 10 cm, the correction will not be successful.

9.2.2 Common Point Method
The common point method is used for hindcast correction in the case where two different stations have been set
up without orientation in the same coordinate system, and two different stations have observed the same
prismatic point. The operation steps are as follows.
1. Pre-condition: there are two direction-free stations and corresponding measurement points, and one of the
measurement points for the two stations set up public observation.
2. Go to [Free Station Correction] and select the Common Point Method. Select STA 1, Known coord 1, STA 2,
