This project will develop a state-of-the-art commercial prototype of the cryogenic sapphire oscillator (CSO) optimised for use at remote sites. Proof of operation will be applied to the important niche market of Very-Long Baseline Interferometry (VLBI) radio astronomy, with improvements in image quality. The research will also significantly benefit the Australian bid for the SKA project, as the CSO is the only technology capable of synchronising the outputs of the telescopes arrays to the required signal to noise to attain the required image quality. The project will further Australia's status in radio astronomy as a world leader and add to our exports of precision scientific instruments.

该项目将开发最先进的低温蓝宝石振荡器（CSO）的商业原型，优化用于远程站点。操作证明将应用于甚长基线干涉测量（VLBI）射电天文学的重要利基市场，并改善图像质量。这项研究也将极大地有利于澳大利亚对SKA项目的竞标，因为CSO是唯一能够将望远镜阵列的输出与所需的信号噪声同步以获得所需的图像质量的技术。该项目将进一步提高澳大利亚在射电天文学领域的世界领先地位，并增加我们精密科学仪器的出口。
