In the framework of the European Gravity Service for Improved Emergency Management(EGSIEM) project, consistent sets of state-of-the-art reprocessed Global Navigation Satellite System(GNSS) orbits and satellite clock corrections have been generated. The reprocessing campaignincludes data starting in 1994 and follows the Center for Orbit Determination in Europe (CODE)processing strategy, in particular exploiting the extended version of the empirical CODE Orbit Model(ECOM). Satellite orbits are provided for Global Positioning System (GPS) satellites since 1994 and forGlobalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS) since 2002. In addition, a consistentset of GPS satellite clock corrections with 30 s sampling has been generated from 2000 and with 5 ssampling from 2003 onwards. For the first time in a reprocessing scheme, GLONASS satellite clockcorrections with 30 s sampling from 2008 and 5 s from 2010 onwards were also generated. The benefitwith respect to earlier reprocessing series is demonstrated in terms of polar motion coordinates.GNSS satellite clock corrections are validated in terms of completeness, Allan deviation, and precisepoint positioning (PPP) using terrestrial stations. In addition, the products herein were validated withGravity Recovery and Climate Experiment (GRACE) precise orbit determination (POD) and SatelliteLaser Ranging (SLR). The dataset is publicly available.
