编队卫星相对运动描述方法综述

Review of Relative Motion Description Methods for Satellite Formation Flying

对于近地轨道卫星编队飞行的相对运动理论研究,可以采用的方法包括直角坐标法和轨道要素法。利用直角坐标法得到的相对运动动力学方程可以用于编队队形控制研究,轨道要素法能够给出相对运动的运动学描述,便于定量研究摄动影响和进行编队队形设计。分析了直角坐标法在描述卫星长期编队飞行方面的局限性,综述了利用轨道要素描述编队卫星相对运动的各种研究方法,包括轨道要素差法、相对轨道要素法和参照轨道要素法等。

Both Cartesian coordinates and orbital elements can be used to theoretically study the relative motion of satellite formation flying maintained in low earth orbit. The dynamical equations of relative motion described by Cartesian coordinates are convenient for orbital control design, while the kinematical equations of relative motion described by orbital elements are suitable for studying perturbation effects and designing formation. This paper analyzes the limitations of Cartesian coordinate method in the description of long - term satellite formation flying, and summarizes various orbital element approaches used to describe relative orbit, including orbital element difference, relative orbital element, and reference orbital element.
