Guidance, navigation and control of small satellites

在过去十年左右的时间里，航天工业经历了从大型昂贵卫星到小型卫星的范式转变。 廉价卫星小型和超小型卫星具有许多优点。他们明显少 比大型卫星还贵。这一事实本身就使它们具有吸引力，特别是使它们易于获得， 希望开展在轨科学研究的大学（在工业和空间机构的支持下）。小 卫星是卫星编队飞行的赋能技术。这是一个当前非常感兴趣的话题 在加拿大和世界各地。 几乎所有空间系统的一个基本组成部分是制导、导航和控制系统。 有大量的文献致力于一般GNC理论。然而，在以下方面存在差距： 理论和实践的最新发展。在某些情况下，理论领先于实践， 有的则是实践先于理论。 这项研究计划的长期目标是应用先进的制导、导航和控制技术 （b）为当前和预期的未来空间系统，特别是为小型和非常小型的卫星提供技术支持。的 目的是为设计人员提供一套指导方针和工具， 具有可证明保证的稳定性和性能的空间系统问题的最新GNC算法 在真实的条件下保证金。这将涉及理论和实验研究。短期 术语，意图是集中在航天器编队飞行问题。 拟议的研究有可能大大推进空间系统GNC实践的现状， 特别是对于小型和非常小型的卫星。反过来，这将提高这些系统的能力。 鉴于加拿大工业界、学术界和 这将有助于加拿大走在这些技术的最前沿。

Over the past decade or so, the space industry has seen a paradigm shift from large expensive satellites to small inexpensive satellites. Small and very small satellites have a number of advantages. They are significantly less expensive than large satellites. This fact alone makes them attractive, in particular making them accessible to universities (with support from industry and space agencies) wishing to perform on-orbit science. Small satellites are an enabling technology for satellite formation flying. This is a topic of significant current interest within Canada and worldwide. An essential component of almost all space systems is the Guidance, Navigation and Control (GNC) system. There is a wealth of literature devoted to the theory of GNC in general. However, there exists a gap between the state-of-the-art in theory and the state-of-the-practise. In some cases, the theory is ahead of the practise, and in other cases, the practise is ahead of the theory. The long-term objective of this research program is to apply advanced guidance, navigation and control techniques to current and anticipated future space systems, in particular for small and very small satellites. The intent is to provide designers with a set of guidelines and tools for the application of implementable state-of-the-art GNC algorithms to space system problems with provably guaranteed stability and performance margins under real conditions. This will involve both theoretical and experimental investigations. In the short term, the intention is to focus on the spacecraft formation flying problem. The proposed research has the potential to greatly progress the state-of-the-practise of GNC of space systems, in particular for small and very small satellites. In turn, this will increase the capabilities of such systems. Given the increasing interest in small and very small satellites within Canada in industry, academia and government, this will assist in placing Canada at the forefront of these technologies.
