10.2 Setting a station and orientation

Please pay particular attention to the information given in this section.
Setting a station is one of the most important operations when using a total station and must be carried out with great
care.
One of the simplest and most reliable methods of achieving this involves setting up the tool over a (known) point on
the floor or ground and using a reliable target point.
The possibility of setting the station "anywhere" offers greater flexibility but presents risks in that errors may not be
identified and then transferred or multiplied as the work proceeds, etc...
Moreover, this possibility requires a little experience in selecting a position for the tool relative to the reference points
used for position calculation.
NOTE
Please remember: If the station is set incorrectly, everything measured subsequently from this station will also be
incorrect – i.e. the actual applications carried out such as measuring, layouts or staking out, etc...

10.2.1 Overview

In certain applications that make use of absolute positions, after physically setting up the tool, i.e. setting up the
station, it is also necessary to set the position of the station with the applicable data, as in the application it is
necessary to know the position at which the tool is standing.
This position can be defined by way of coordinates or by establishing a building control line.
This process is called Set station.
In addition to the position of the tool it is also necessary to know in which direction the reference axes lie or,
respectively, the direction of the main axis.
In most cases where coordinates are used, the main axis runs northwards. Where control lines are used the main axis
lies in the direction of the control line.
It is necessary to know the direction of the reference axis as the horizontal circle and its "zero mark" is, so to speak,
rotated parallel to or in the direction of the main axis.
This process is called Orientation.
The alternative ways of setting the station can, so to speak, be used in two systems.
They can be used either in a building control line system where lengths and offset distances exist or are entered, or in
a perpendicular coordinate system.
The station system or, respectively, the measuring system is fixed with the definition of the station.
