A computing system (CS) calculates a three-dimensional (3D) position of an origin of a 3D upperworks coordinate system for a crane based on local coordinates of the crane. The origin is located along an axis of rotation between an upperworks of the crane and a lowerworks of the crane that is rotatably coupled with the upperworks. The CS transforms the 3D position of the origin from the local coordinates to global 3D coordinates using absolute position sensing data from first and second positioning sensors attached to the crane and using global 3D coordinates specific to the jobsite where the crane is located. The CS computes positions of at least one movable component of the crane with respect to a tracked object on the jobsite. The CS utilizes the computed positions to provide assistance in maneuvering the crane with respect to the tracked object.
