Abstract

Geodetic Very Long Baseline Interferometry (VLBI) is vital for precise Earth rotation and orientation measurements. The International VLBI Service for Geodesy and Astrometry (IVS) collaboratively collects VLBI-related files from global institutions. This project consolidates performance metrics from IVS submissions into a common database with session-, station-, and source-based tables. It offers open access through a web interface and API, enabling quick program adjustments with online plotting tools. These databases optimize observing plans by excluding underperforming elements. This enhances data accuracy and fosters VLBI community collaboration, advancing open research data initiatives in Earth sciences and geodesy, particularly for the IVS community.
