The U.S. Geological Survey intends to award a sole-source purchase order to Earthscope Consortium, Inc. for continuous GNSS data archiving, curation, and dissemination services. The period of performance is from August 1, 2026, through June 30, 2031, including four 12-month option years. Services will be performed for the Virginia-West Virginia Water Science Center, with no specific budget amount provided. The requirement includes routine annual archiving for active stations and a one-time ingestion of historical data for a legacy station. This is not a competitive solicitation, as Earthscope is uniquely qualified as the only USGS-approved repository for this data.
