This project aims to realise real-time kinematic precise orbit and attitude determination of nano satellites. Formation flying, based on distributed miniaturised satellites such as Cubesats, is envisioned to revolutionise the way the space-science community conducts autonomous missions. The project will develop a purely kinematic concept exploiting the full capabilities of Global Navigation Satellite Systems (GNSS) carrier-phase measurements for instantaneous precise orbit and attitude determination of the Cubesats. The project will also pioneer the use of the satellite based augmentation systems (SBAS), supporting the future Australian SBAS program, and the development of integrated algorithms for space-based, Precise Point Positioning with fixed ambiguities supported by SBAS.

该项目旨在实现纳米卫星实时运动精确定轨和定姿。基于立方体卫星等分布式小型卫星的编队飞行有望彻底改变空间科学界执行自主任务的方式。该项目将开发一个纯粹的运动学概念，利用全球导航卫星系统（GNSS）载波相位测量的全部功能，实现立方体卫星的瞬时精确轨道和姿态确定。该项目还将率先使用星基增强系统（SBAS），支持未来的澳大利亚 SBAS 计划，并开发 SBAS 支持的具有固定模糊度的天基精确单点定位集成算法。
