SURVEYING TARGET AND METHOD WITH LIGHT SECTOR POWER OPTIMIZATION

A target () for use in surveying applications is provided. The target comprises a plurality of light sources () arranged around a longitudinal axis (A) of a base element () of the target. The plurality of light sources is configured to emit light radially. The target further comprises a sensor unit () a control unit (). The control unit is configured to obtain information regarding an orientation (α) of said target relative to a surveying instrument () aimed at the target, based on at least a measurement received from the sensor unit. The control unit is further configured to identify, based on the obtained information regarding the orientation of the target relative to the surveying instrument, a first subset (-) of the plurality of light sources arranged to emit light towards the surveying instrument, and a second subset (-) of the plurality of light sources arranged to emit light away from the surveying instrument. The control unit is further configured to control the plurality of light sources such that the first subset of light sources emit light with a higher intensity than the second subset of light sources.
