This option applies an additional displacement to an existing local system, allowing the correction of any differences there may be between the current coordinates of the reference base and their corresponding project coordinates.

 

 

 

If the mobile receiver is restarted and this option is used again, Use Current Displacements is permitted which are applied to the local system, avoiding having to acquire the points again to calculate the displacements. Confirmation is requested as well as showing said displacements.

 

The Insert button allows points to be added with known coordinates to calculate the displacements which must be applied. Every time a new point is added, the residuals at x, y, z are calculated for each. Furthermore, the maximum horizontal and vertical errors of the set of points read are shown.

 

 

By pressing the GPS button the current coordinates are read and they are transformed in accordance with the calibration system selected in the project (no additional displacement is applied). The point can be read with epochs.

 

In the Destination section an indication must be provided of the coordinates in the local system which correspond to the current base.

 

The Delete button deletes the selected point from the list in such a way that it ceases to form part of the set of points with which the displacements are calculated.

 

The dialog not only shows the residuals in x, y, z but also the maximum horizontal and vertical errors found.
