This project aims to implement the completely new concept of observing artificial satellites with radio telescopes, realising a so-called space tie. Understanding Earth’s changing shape requires measurements with a stability of 0.1 mm per year. Today, geodetic earth observations are used to realise reference points with a precision of five to ten times larger. Using the unique Australian ground infrastructure, current observational and operational problems shall be overcome. The intended outcome is to improve the coordinate system of the Earth, which is the basis for a better understanding of Earth serving to fulfil scientific as well as societal demands.

该项目旨在实现用射电望远镜观测人造卫星的全新概念，实现所谓的空间联系。了解地球形状的变化需要每年0.1毫米的稳定测量。今天，大地测量观测被用来实现参考点的精度是5到10倍。利用澳大利亚独特的地面基础设施，将克服当前的观测和操作问题。预期的结果是改进地球的坐标系统，这是更好地了解地球的基础，有助于满足科学和社会的需求。
