Description of the System
AT500 Instrument Measurement System
Angular System
The angle measurement system mainly consists of a coded glass circle and
four angular encoders using quadruple angle reading. The quadruple angle
reading system eliminates systematic and periodical errors of the angle
measurement which results in increased measurement accuracy.
Inclination Sensor
The Absolute Tracker AT500 features a dual-axis Orient-to-Gravity sensor.
This inclination sensor is located within the rotating head of the AT500
instrument. The Orient-to-Gravity sensor can operate in different modes
depending on the stability of the ground:

Refer to Tracker Pilot Reference Manual or the relevant third-
party software application manual for details on setting the
desired operation mode.
Motorisation
The AT500 instrument has two orthogonal, rotating axes. The motorisation
of the axes uses direct drives that provide highest tracking speed and accel-
eration for high-dynamic measurements, for example in automation applica-
tions.
