| Popis: | The present paper provides an overview on the design of a new Satellite Laser Ranging (SLR) system, the Satellite Observing System Wettzell (SOS-W). It pays special attention on the local survey, the determination and monitoring of the ties between the established Wettzell Laser Ranging System (WLRS) and the SOS-W. We also introduce an alternative normal point algorithm, which demonstrated fewer systematics in the resulting normal point statistics compared to the standard approach of iterative data editing. Having two highly productive SLR stations on site allows for a rigorous comparison between local survey derived ties and space segment derived ties. One-year observations to the Laser Geodynamic Satellite (LAGEOS) have been processed, and a multitude of different solutions has been calculated. The results show agreement in the sub-millimeter range with respect to the local survey. |
