## Abstract

A surveying appliance for surveying targets has a targeting unit and a remote control unit for prompting changes in the orientation of the targeting unit, equipped with measurement functionality for determining a three-dimensional orientation of the remote control unit or for determining movements by the remote control unit. The surveying appliance also has an evaluation and control unit. The extent or speed of the changes in the orientation of the targeting unit can be scaled to corresponding changes in an orientation or speed of change of orientation of the remote control unit such that at least two targeting modes having different levels of transmission ratio are provided. The surveying appliance can be used with corresponding handheld, moving remote control units, computer program products for providing, controlling and performing a targeting functionality for the surveying appliance and methods for tracking and surveying targets using the surveying appliance.
