Entwicklung, Kalibrierung und Erprobung eines kameraunterstützten Hängetachymeters
Despite all technical enhancements in the past modern electronic tacheometers do not differ significantly to their analogue predecessors. All have in common that aiming around the nadir is not possible. This means that points situated in the zenith angle region between ca. 170 to 230 gon cannot be measured directly. Therefore the subject of the present work was the development of a system that makes measurements in the zenith angle region between 170 and 230 gon possible. The concept is based upon the suspended theodolite which is known in mine-surveying. To carry out measurements in the region of the nadir a total station is mounted in a hanging position similar to a suspended theodolite. However the function of the tilt compensator which is used for levelling of the instrument is not supported in this position. Hence inclination is monitored externally. For this purpose the tacheometer is connected to a clinometer by an appropriate suspension arrangement. The combination of a tacheometer mounted in a suspended position and an external clinometer is called suspended tacheometer...
