A geodetic target for use in geodesy includes a support, a measuring target supported by the support, an identifier supported by the support, and a controller. The identifier includes at least one identification element that is configured to be switchable between at least two optical states and has a first predetermined optical property in one optical state and does not have the first predetermined optical property in a further optical state. The controller is configured to change the state of the at least one identification element. A geodetic measurement instrument includes an identifier detection unit, a measuring unit, and a transmitter configured to address a receiver of the geodetic target and to transmit control commands to the same which effect the change of the optical state of the at least one identification element of the identifier of the geodetic target. A system includes the geodetic measurement instrument and geodetic target.
