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： A surveying system for measuring the position of a measuring point, the surveying system including a survey pole with a pointer tip for contacting the measuring point, and position giving means for making available the coordinative determination of a referenced position, the position giving means being placed on the body with a defined spatial relationship relative to the tip, a control and evaluation unit for deriving the position of the measuring point at least based on the determined referenced position and on the defined spatial relationship of the position giving means relative to the tip, and an inertial measurement unit comprising IMU sensors, a motion tracker configured to derive motions and/or motion patterns of the survey pole, wherein, if a derived motion or motion pattern corresponds to a defined motion pattern, the surveying system is configured to automatically perform an action associated with the defined motion pattern.
