洛伦兹增强轨道(LAO)概念是一种不带系绳的电磁推进系统，它利用带静电的航天器与地球磁场之间的相互作用来提供有用的推力。在近地轨道(LEO)中，作用在相对于地球磁场飞行的带电航天器上的洛伦兹力会在垂直于其速度和磁场的方向上产生加速度。本文研究了低轨编队飞行中利用洛伦兹力推进航天器的概念。以三角形航天器编队构型为例，对该构型的优缺点进行了仿真验证。结果表明，仅使用洛伦兹力就可以进行简单的编队动作。
The Lorentz Augmented Orbit (LAO) concept is an electromagnetic propulsion system without a tether that uses the interaction between an electrostatically charged spacecraft and the Earth's magnetic field to provide a useful thrust. In Low Earth Orbit (LEO), the Lorentz force acting on a charged spacecraft flying relative to Earth's magnetic field causes acceleration in a direction perpendicular to both its velocity and the magnetic field. In this paper, the concept of spacecraft propulsion using Lorentz force is investigated for LEO formation flying. A triangular spacecraft formation configuration is used to simulate and validate the advantages and disadvantages of the proposed concept. It is illustrated that simple formation manoeuvres can be performed solely using the Lorentz force.
