Setting up a station using multiple point resection
A resection sets up the station using angle/distance measurements to known points.
You can use a maximum of 10 points in a resection. Measurements can be distance
and angle, or angle only. Calculation starts automatically when enough measurements
are taken.
You can delete poor observations and recalculate if necessary. You can also select the
BS point.
1. To start the resection, press
[2]
or select
Resection
in the Stn Setup menu.
2. Enter the point name for the first observation
point (PT1).
3. Enter the target height and press
[ENT]
.
If the angle between known point 1 and known point 2 (measured from the station point) is extremely acute or
extremely oblique, the resulting solution will be less reliable geometrically. For geometric reliability, select known
point locations (or station point locations) that are widely spaced.
