Achieving millimetre geodesy with space tie satellites

该项目旨在实现用射电望远镜观测人造卫星的全新概念，实现所谓的太空纽带。要了解地球不断变化的形状，需要以每年0.1毫米的稳定性进行测量。今天，大地测量被用来实现精度高达五到十倍的参考点。利用澳大利亚独特的地面基础设施，将克服目前的观测和操作问题。预期的结果是改进地球的坐标系，这是更好地了解地球的基础，有助于满足科学和社会需求。

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.
