Remote Height
Introduction
This manual describes the "Remote
Height" program of the TPS1100
Professional series.
Remote Height is used to determine
the elevation of inaccessible points,
e.g. on cables or building facades.
First, the distance to a base point
situated vertically below (or above)
the remote height point must be
measured. Then you can aim to the
remote height point.
The coordinates of the remote point
are calculated from the distance
measured to the base point and from
the angles measured to the remote
point.
To ensure correct results, the target
and the reflector must be lined up
vertically. In practice it is not
generally possible to maintain an
exactly-vertical line, and so you must
decide what lateral deviation can be
tolerated.
The horizontal distance to the
inaccessible target must however
coincide with the horizontal distance
to the reflector.
When the instrument is aligned and
the station coordinates have been
set, the position coordinates of the
remote height can be calculated and
stored in the measurement job. Measure Base Point
This dialog is used in accordance
with the settings of the system
function "Measure & Record" or

Point Id
The point number of the base point.
Hz
