results are to be obtained using this method, it is important
that the traverses and networks are of high quality. For this
reason we have provided the Free Station routine with a
function called Config. (configuration). This allows you to
use factors such as the scale factor (stored under label = 43),
weight factors to weight your points with regard to the
distance from your free station to the known point (used
mainly in Germany), and also to create a point list in which
all measured data for each individual measured point can be
made available for editing and possible recalculation. In the
example on page 1.3.33 we have choosen not to use Config.
but to treat it separately on page 1.3.47.
Free station establishment can be done with a large number
of different combinations of points, angles, and distances
(see Fig. 3.6)
With free station establishment using 3-10 known points, the
following combinations are possible:
1. Angles and distances
2. Only angles. But note that three points alone will not
provide enough data to be able to calculate an optimal
solution — that is, they will not give a standard deviation.

Note ! ☛
If only 3
angles
are used,
try to
establish

the
”triangle”
in order
to avoid
the
”dangerous
circle”.
