List of radio astronomy stations as a database for sharing and compatibility studies

In the evolving landscape of spectrum sharing between radio astronomy observatories and satellite operators, the interplay between them becomes more and more important. Historically it was national administrations to support data exchange between different radio spectrum users. However, with rapid satellite development a need for a more global approach arises.

Our discussion extends to the development and utilization of a CPS-based database, incorporating data from a snapshot of the Master International Frequency Register (MIFR) to house radio astronomy observatories' characteristics. This database not only serves as a vital resource for sharing and compatibility studies within the IAU CPS framework but also addresses gaps in existing registries by including data from unfiled observatories, like the South Pole Telescope.

Furthermore, we introduce a novel tool designed to help those with access to the ITU database, allowing for efficient retrieval of radio astronomy station data. This tool, aimed at both the radio astronomy and satellite communities, promises to streamline the process of conducting sharing and compatibility studies by providing comprehensive access to essential parameters, including station and antenna specifics, frequency bands, and operational details. This initiative represents a significant step forward in ensuring the harmonious coexistence of satellite and radio astronomy operations, bolstering the efficacy of global regulatory frameworks.
