This project aims to combine cubesat and hybrid cubesat/micro-satellite concepts studied in Australia and Japan, prototyping and space-qualifying the most custom components, enabling a future affordable launch. High angular resolution is critical for studying processes of star formation, black holes, and exoplanets. An array of small satellites can greatly exceed the angular resolution of a single telescope, or the sensitivity of atmosphere-limited ground-based interferometers. Space qualifying the key inter-spacecraft metrology and fibre injection technologies will not only enable a future Australian satellite astrophysical interferometer, but is also relevant for optical communications links and earth observations.

该项目旨在结合澳大利亚和日本研究的立方体卫星和混合立方体卫星/微型卫星概念，对大多数定制组件进行原型设计和空间认证，从而实现未来经济实惠的发射。高角分辨率对于研究恒星形成、黑洞和系外行星的过程至关重要。小型卫星阵列可以大大超过单个望远镜的角分辨率或大气限制的地面干涉仪的灵敏度。对关键的航天器间计量和光纤注入技术进行空间鉴定不仅将使澳大利亚未来的卫星天体物理干涉仪成为可能，而且还与光通信链路和地球观测相关。
