Abstract

We present experimental results of a high-speed 3-D laser scanner developed for the European Space Agency within an activity dealing with a high precision relative attitude control sensor for formation flying. By employing pulsed-time-offlight measurement, we demonstrated sub-mm accuracy and precision as well as unprecedented resolution of single-shot measurements to natural targets at distances up to 150 m. The instrument is based on RIEGL's commercial terrestrial laser scanners with a scan range of 100° x 360° and a net measurement rate of 125 kHz. The system's performance is demonstrated with different test setups and potential fields of application are assessed.
