Australia is increasingly dependent on spatial positioning and spatial data, yet mostly relies upon international agencies and research organisations to provide regular updates of coordinates and reference frame definition used on Earth. Improving the accuracy of the reference frame definition and our understanding of errors in the space-based measurements will provide new insights for studies of the Earth. The research will yield results in studies of national significance, such as sea level rise, the effects of melting polar regions, and crustal deformation, as well as developing Australia's expertise in exploiting observations of the Earth from space.

澳大利亚越来越依赖空间定位和空间数据，但主要依赖国际机构和研究组织定期更新地球上使用的坐标和参考框架定义。提高参照系定义的准确性和我们对天基测量误差的理解将为地球研究提供新的见解，这项研究将在对国家具有重要意义的研究中产生成果，如海平面上升、极地融化的影响和地壳变形，以及发展澳大利亚利用空间观测地球的专门知识。
