摘要：Surveying system for measuring the position of a measuring point (1) on theground, the surveying system comprising a survey pole (10) with a body (13) having apointer tip (12) for contacting the measuring point (1) and position giving means formaking available the coordinative determination of a referenced position, being placedon the body (13) with a defined spatial relationship relative to the tip (12), determinationmeans for repeatedly determining the referenced position of the position giving meansand evaluation means (17) for deriving the position of the measuring point (1), whereinthe survey pole (10) further comprises an inertial measuring unit (18) placed on the body(13) with a defined spatial relationship relative to the position giving means, the surveyingsystem further comprises IMU-processing means for repeatedly determining inertialstate data based on measurements taken by the inertial measuring unit, and theevaluation means (17) are further configured for feeding a predefined filter algorithmwith the repeatedly determined referenced position and the repeatedly determinedinertial state data and deriving therefrom referenced attitude data for the survey pole(10), taking into account the defined spatial relationship of the inertial measuring unit (18)relative to the position giving means, using a DDF within the predefined filter algorithm,and further using the referenced attitude data for deriving the position of the measuring
point (1).
