The further development of space-geodetic station networks and analysis techniques is crucial for the realisation of terrestrial and celestial reference systems as well as to determine the Earth orientation parameters as the link between them with high accuracy and long-term stability. This requires geographically well-distributed and long-term sustained networks for all space-geodetic techniques: Global Satellite Navigation Systems (GNSS), Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS), Satellite/Lunar Laser Ranging (SLR/LLR), and Very Long Baseline Interferometry (VLBI).
The fundamental importance of geodetic reference frames has been recognised by the United Nations (UN) General Assembly resolution 69/266 on ‘A Global Geodetic Reference Frame for Sustainable Development’, adopted on 26 February 2015. The Global Geodetic Observing System Committee on Performance Simulations and Architectural Trade-Offs (GGOS-PLATO) investigates how to enhance the space-geodetic infrastructure designed (i) to acquire observations larger in quantity and better in quality by enhanced and additional ground stations, as well as (ii) to better tie the observation systems, e.g., by more co-locations on ground or in space, like ESA’s upcoming Genesis mission which will allow realising space ties between all four techniques for the first time.
This presentation provides an overview of recent GGOS-PLATO-related efforts regarding the sustainability and potential development of the existing networks of all space-geodetic techniques, including the aspect of co-located sites for the realisation of the terrestrial reference frame. The GGOS-PLATO studies aim to support the goals of the United Nations Global Geodetic Centre of Excellence (UN-GGCE), established in 2023 to coordinate the implementation of the UN resolution.
