The German Satellite Positioning Service GEPOS® is the high accurate satellite positioning service of the federal government. Based on BKG’s GREF GNSS reference station network, the SAPOS® network of the surveying authorities of the German Laender and supplemented by additional reference stations of neighboring countries the service provides uniform correction data in state space for entire Germany including its exclusive economic zone. The correction data is published in the openly specified SSRZ data format and broadcasted both via the internet and via a data channel of digital radio DAB+. The service enables positioning with an accuracy of a few centimeter in the German national reference frame ETRS89/DREF91 (R2025) using PPP-RTK technology. With its transition to operational use, GEPOS®, as an element of Germany's digital infrastructure, will provide a foundation for value-added services with spatial reference in the public administration, science and business sectors starting in 2027. The correction data are subject to an open data license and are made available free of charge and with low barriers to access to users within the federal administration and all other users alike. The presentation outlines the rationale behind and implementation of GEPOS®, addressing the mechanisms established to ensure product quality and availability. Concrete application examples from the federal administration offer insights into usage scenarios and demonstrate the capabilities of the new service.
