The current objectives of the GGOS-FA-UHS focus on the implementation of the International Height Reference System (IHRS), in particular:
the compilation of detailed standards, conventions, and guidelines to make the IAG Resolution applicable.
the establishment of the International Height Reference Frame (IHRF) as the realization of the IHRS.
the evaluation of the achievable accuracy under the present conditions (data availability, computation methods, etc.) and the identification of key actions to improve the determination of the IHRF coordinates.
the development of an operational infrastructure within the International Gravity Field Service IGFS) to ensure the maintenance and availability of the IHRF in a long-term basis.
