Objectives

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.
