Real time DGPS service for precise positioning-activities in the Federal Republic of Germany

Based on a strong user request for precise real-time satellite based positioning systems, the German Institute of Navigation has started an initiative within its commission Space Techniques to work on the topic of precise real-time DGPS. The aim of these activities is to develop a concept for a real-time DGPS service providing an accuracy better than 3 m up to the centimeter level. The author presents the current status of the project and its first results, and provides an overview of the work on precise DGPS and GLONASS in Germany. In addition, the outcome of the DGPS '91 symposium in Braunschweig is discussed.<
