Two new radio telescope arrays are under construction in Australia. One is the Australian Square Kilometre Array Pathfinder, near Geraldton. The other is a very long baseline array with antennae near Hobart, Katherine, and Yarragadee. These three antennae work together to observe radio sources far away across the universe. Their observations are used to establish a very accurate coordinate system or reference frame on the earth, to which the global positioning system is aligned. This program will use these new radio telescope arrays to study the Milky Way and other galaxies, and to study continental drift and sea-level rise on the Earth.

澳大利亚正在建造两个新的射电望远镜阵列。一个是杰拉尔顿附近的澳大利亚平方公里阵列探路者。另一个是在霍巴特、凯瑟琳和雅拉加德附近有天线的非常长的基线阵列。这三根天线一起工作，以观测遥远的宇宙中的射电源。他们的观测被用来在地球上建立一个非常精确的坐标系或参考框架，全球定位系统与之保持一致。这个项目将使用这些新的射电望远镜阵列来研究银河系和其他星系，并研究地球上的大陆漂移和海平面上升。
