ANGLE MEASUREMENT SYSTEM CHAPTER 1
GEODIMETER SYSTEM 600
Overview
The Geodimeter System 600 meets all demands for efficient
and accurate angle measurement. It also allows you to
choose the measuring method with which you feel most
comfortable. The angle measurement system gives you full
compensation for the following:
Automatic correction for angle sensor errors.
Automatic correction for collimation error and trunnion
Axis tilt.
Automatic correction for tracker collimation error.
Arithmetic averaging for elimination of pointing errors.

The Angle Measuring Technique
One of the strong features of the design of Geodimeter
System 600 is its electronic angle measurement system, which
eliminates the angle errors that normally occur in conventio-
nal theodolites. The principle of measurement is based on
reading an integrated signal over the whole surface of the
angle sensor and producing a mean angular value. In this
way, inaccuracies due to eccentricity and graduation are
eliminated.
Dual Axis Compensator
The instrument is also equipped with a dual axis compensa-
tor which will automatically correct both horizontal and
vertical angles for any deviations in the plumb line. The
system warnes immediately of any alterations in excess of
±10
c
(6').
