Modified Algorithm for Dynamic Telescope Reference Monitoring

The GeoMetre project partners Frankfurt University of Applied Science and Bundesamt für Kartographie und Geodäsie (BKG) have developed a new algorithm for dynamic reference point determination of VLBI and SLR telescopes which considerably eases the synchronization requirements for telescope and measurement system. The new approach allows for an in-process metrological determination of the reference point. It has been successfully implemented and validated at the Geodetic Observatory at Wettzell. The movie shows an mobile laser tracker measuring positions of targets mounted on the moving SLR telescope in the measurement process. The target positions for each telescope orientation are then used to determine the location of the telescope’s reference point. Knowledge of the exact location is critical for the correct spatial referencing of the telescope’s observation data.
