The EUREF Permanent Network: Monitoring and On-line Resources

Abstract

The EUREF Permanent Network (EPN) is a network of continuously operating GPS or GPS/GLONASS stations installed throughout the European continent. The EPN Central Bureau (CB), responsible for the daily management of the EPN, uses several monitoring procedures to verify the meta-data, latencies and quality of the observation data files in order to assess if the data meets the requirements of the analysis. In addition, several types of coordinate time series allow analysing the long-term stability of the site coordinates. All monitoring procedures result in regularly updated plots made available at the EPN CB website; they are created to be easily understood by all EPN station managers, even the non-specialists. This paper outlines the on-line resources available from the EPN Central Bureau and summarizes the procedures used to obtain this information.
