The Hartebeesthoek Radio Astronomy Observatory (HartRAO) hosts two research programmes: radio astronomy and space geodesy. The Space Geodesy programme has four main co-located space geodetic techniques, making HartRAO a true fiducial site. These techniques are Global Navigation Satellite Systems (GNSS), Satellite Laser Ranging (SLR), geodetic Very Long Baseline Interferometry (VLBI) and Doppler Orbitography and Radio-positioning Integrated by Satellite (DORIS). Only GNSS data are stored on-site in a publicly accessible repository. The HartRAO Space Geodesy Programme is expanding its geodetic techniques with Lunar Laser Ranging (LLR) as well as a network of seismometers, accelerometers, tidal gauges and gravimeters. These instruments will be installed across the southern African region and will generate large volumes of data that will be streamed to and stored at HartRAO. Our objective is to implement a complete Geodetic Research Data Management System (GRDMS) to handle all HartRAO’s geodetic data on-site in terms of archiving, indexing, processing and extraction. These datasets and subsequent data products will be accessible to both the scientific community and general public through an intuitive and easy to use web-based frontend. As the first step in this process, we are currently working on establishing a new data centre. This opens up the possibility for the librarian to provide data services and support by working together with researchers and information technology staff. We discuss the rationale, role players and top-level system design of this GRDMS, as well as the current status and planned products thereof.
