Abstract
A low-profile theodolite leveling means comprises a tribrach assembly including three separate platforms of which the second is mounted upon the first by means of a pair of pivot elements which establish a first fixed axis of tilt of the second platform, and the third is similarly mounted on the second by means of a pair of pivots which likewise establish a second fixed axis of tilt, orthogonal to the first axis, for the third platform. Located in use between a tripod head and the base of a theodolite geodetic instrument, the tribrach assembly provides means for tilting the theodolite instrument with respect to independent planes defined by the orthogonally disposed axes of tilt and respective adjustment screw members.
