• Abstract:
  The Oregon Real-Time GNSS Network (ORGN), managed by the Oregon Department of Transportation, serves as a critical backbone for high-precision positioning services across the state. However, the absence of a streamlined workflow for aligning ORGN station coordinates to the National Spatial Reference System (NSRS) has introduced challenges in consistency, traceability, and long-term network maintenance. This project developed and validated a semi-automated alignment tool, ORGN Align, that integrates baseline design, RINEX data management, OPUS Project adjustment, and time-series visualization into a unified platform. Unlike fully automated systems, ORGN Align emphasizes operator oversight and interpretability, empowering GNSS network managers to make informed decisions regarding coordinate adoption and network integrity. This report outlines technical implementation, system capabilities, and recommendations for integration into operational practice, offering a scalable model for GNSS network alignment applicable to other state and institutional networks.
