Updates to the IGS Data Center Infrastructure

The global data centers are key components of the IGS infrastructure, providing access to a full suite of GNSS data, products, and information. These archives are essential tools for a diverse international scientific user community. Since the start of the IGS in 1992, the number of stations, types of station data and derived products has increased substantially, requiring modifications to data center operations. Updates to the archives occur due to new data and products, re-publishing of previously archived data and products, transmission of historic data, and the resulting re-distribution of these data and products from data center to data center. In addition, statistics on the usage of the data and products are important to the data centers as well as data and product providers. This poster will review the status of the IGS data center infrastructure and present ideas, both near-term and long term, for data center equalization and validation of data holdings, modernization of compression schemes, and reporting of usage statistics
