摘要： A surveying instrument, comprising at least one rotational movement axis such as a azimuth axis, which is for providing a positioning of the measurement direction of the surveying instrument, a rotational position encoder configured for deriving a rotational direction value around the movement axis and an acceleration sensor such as a MEMS-accelerometer for deriving a leveling for the surveying instrument and being rotatable around the rotational movement axis in different rotational positions. The instrument further comprises a mechanism designed to move the accelerometer from a first orientation in at least a second orientation, the second orientation being different to the first orientation, wherein the mechanism is designed and arranged in such a way that the targeting direction is uninfluenced by a movement of the accelerometer by the mechanism, and an evaluation unit configured to derive a calibrated leveling for the instrument.

摘要： An inclination sensor for determining an angle of inclination relative to the gravitational vector comprising a fluid container and a first pressure sensor pair having a first and a second pressure sensor arranged in an edge region of the fluid container such that they are connected to each other by the connecting fluid and have a fixed and defined positional relation to each other. The first and the second pressure sensor are each configured to measure a hydrostatic pressure in the connecting fluid. A processor is configured to determine a relative height (h) in the direction of gravity between the first and the second pressure sensor based on the hydrostatic pressures measured, and to determine an angle of inclination with respect to the gravitational vector based on the determined relative height (h) and the known fixed locations of the pressure sensors within the fluid container.

摘要： A method for determining a calibrated leveling of a surveying instrument with an accelerometer. The method includes moving the accelerometer around a rotation axis of the instrument, the accelerometer being arranged at a known position from the rotation axis. As the accelerometer is moved, acquiring a movement profile of the movement by a rotational position encoder for the rotation axis and sensing an acceleration of the moving as accelerometer readings. Deriving at least one calibration parameter for the accelerometer readings is based on the movement profile, the known position and the corresponding accelerometer readings. A calibrated leveling is provided to the surveying instrument by applying the calibration parameter to the accelerometer readings.
