7.2 Station Setup
7.2.1 Starting
Description Station Setup is a program used when setting up a station, to determine the station
coordinates and station orientation. A maximum number of 10 known points can be
used to determine the position and orientation.
Setup methods The following setup methods are available:
Each setup method requires different input data and a different number of target
points.
P0 Instrument station
P1 Known point
P2 Known point
P3 Known point

Setup method Description
Orientation with Angle The station is known. Aim at a target to set the
orientation.
Orientation with Coordinates The station and target coordinates are known. Aim
at a target to set the orientation and height.
Height Transfer The station is known, a new station height must be
computed. Measure to one or more known targets
to compute new height for the station.
Resection The station is unknown. Measure to two or more
target points to compute station coordinates and
orientation. Scale setting is configurable.
Helmert Resection The station is unknown. Measure to two or more
target points to compute station coordinates and
orientation. The measured angles and distances are
adjusted, based on coordinates of a local and global
system.
A 2D Helmert transformation is used, with four
(shift x, shift y, rotation and scale) or three (shift x,
shift y, rotation) parameters, depending on the
scale setting in the configuration. Points can be
defined as 1D, 2D or 3D.
Local Resection The station is unknown. Measure distances to two
points:
• To the origin (E = 0, N = 0, H = 0) of the coor-
dinate system
• To a point the North or East direction of the
coordinate system
Scale and standard deviation are not calculated.
