ABSTRACT:
A multiple beam path surveying instrument is provided, which possesses an upper part that is rotatable about a vertical axis and which comprises a telescope body that can be swiveled about a tilt axis, with the vertical and tilt axes orthogonally intersecting at an intersection point S. At least two optical arrangements with optical beam paths are set up inside the telescope body. Driving and/or adjustment devices are provided for rotating the upper part about the vertical axis and the telescope body about the tilt axis. Further, measuring systems for determining the rotational angle of the upper part of the survey instrument about the vertical axis and the telescope body about the tilt axis are provided. A computer system may be used to evaluate the measurements, determine, display and/or record the measurement results, as well as to control the driving and adjustment devices for the telescope body and the upper part.
