Introduction
The Global Geodetic Reference Frame (GGRF) is the realisation of the Global Geodetic Reference System (GGRS). The GGRS comprises terrestrial and celestial components allowing users to precisely determine and express locations on the Earth, as well as to quantify changes of the Earth system in space and time.
What is the GGRF?
GGRF has been developed to support the increasing demand for positioning, navigation, timing, mapping, and geoscience applications. It is an essential development for a reliable determination of monitoring changes in the Earth system, natural disaster management, sea-level rise and climate change amongst many other things. The GGRF has also come about due to globalization and the need for universal interoperability requirements across geospatial technologies.
