The UN Committee of Experts on Global Geospatial Information Management (UN-GGIM) recognized since its inception the growing demand for more precise positioning services, the economic importance of a global geodetic reference frame and the need to improve the global cooperation within geodesy. UN-GGIM created a Working Group for a Global Geodetic Reference Frame (GGRF), who formulated and facilitated a draft resolution for a Global Geodetic Reference Frame (GGRF), which was adopted by UN-GGIM in July 2014 and ECOSOC in November 2014. On 26 February 2015, the United Nations General Assembly adopted the UN resolution on Global Geodetic Reference Frame for Sustainable Development that was led by the Republic of Fiji. The Global Geodetic Reference Frame (GGRF) is a generic term describing the framework which allows users to precisely determine and express locations on the Earth, as well as to quantify changes of the Earth in space and time. Most areas of science and society at large depend on being able to determine positions at a high level of precision. At present the GGRF is realized through the International Terrestrial Reference Frame (ITRF), International Celestial Reference Frame (ICRF) and physical height systems.
