Remote Controlled Corner Reflectors

Ferngesteuerter Cornerreflector
Remote controlled “Kalibri” C-band transponder, deployed within the DLR calibration field which is located in South Germany. By means of the two-axes positioner the transponder is remotely aligned towards the satellite from Oberpfaffenhofen, currently for Sentinel-1A and Sentinel-1B overpasses.

DLR corner reflector
Remote controlled DLR corner reflector with a leg length of 2.8 meter.

The Institute utilizes corner reflectors for different purposes and of various sizes. In 2014, the large number of corner reflectors was extended by the first remote-controlled corner reflectors with a leg length of 2.8 meter and a form tolerance of 1 millimeter. In between data takes  the remote controlled corner reflector is turned upside down (as shown in Figure and Video), in a parking position in order to protect the opening from precipitation. As part of the DLR calibration site these targets are located in Southern Germany and are available to support SAR missions worldwide.
