Station Setup Results

The computation of the station position is done via the Method selected in
Enter Station Data.
If more than the minimum required measurements are performed, the proce-
dure uses a least squares adjustment to determine the 3D position and aver-
ages orientation and height measurements.
The original averaged face I and face II measurements are used for the
•
computation process.
• All measurements are treated with the same accuracy, whether these are
measured in single or dual face.
Easting and Northing are determined by the least squares method, which
•
includes standard deviation and improvements for horizontal direction and
horizontal distances.
The final height (H) is computed from averaged height differences based
•
on the original measurements. For the methods Ori. with Coord. and H-
Trans the height can be selected from old, average and new.
• The horizontal direction is computed with the original averaged face I and
face II measurements and the final computed plan position.
Press F4 Compute in the Station Setup Result screen.
This screen displays calculated station coordinates. The final computed results
depend on the Method selected in Enter Station Data.
Standard deviations and residuals for accuracy assessments are provided.
☞ If the instrument height was set to 0.000 in the setup screen, then
the station height refers to the height of the tilting axis.
Description
If the standard deviation for position in East
and North is calculated, a checkbox is dis-
played. The checkbox is checked if the calcu-
lated position is within the standard devia-
tion limits or crossed if it is not.
If the standard deviation for Height is calcu-
lated, a checkbox is displayed. The checkbox
is checked if the calculated Height is within
the standard deviation limits or crossed if it
is not.
If the standard deviation for the Hz Orienta-
tion angle is calculated, a checkbox is dis-
played. The checkbox is checked if the calcu-
lated Hz Orientation is within the standard
deviation limits or crossed if it is not.
