In this application, the lorentz force generated by the interaction between the current in the wire and the geomagnetic field produces an electro - dynamic drag leading to a fast orbital decay. in this paper, we make an intensive study of the process of de - orbiting using electro - dynamic tether system. the concrete work includes : firstly, i have studied the basic principle of how to generate the electro - dynamic drag, modeled via accuracy geomagnetism, made a concrete analysis of the de - orbiting duration, the magnitude and direction of electro - dynamic drag under the action of the dipole and accurate geomagnetic models, set up a counterbalance between electro - dynamic torque and gravity gradient torque, emulate the de - orbiting process of spacecraft, and compared the change of six orbital factors and the de - orbiting duration under the action of the dipole and accurate geomagnetic models
本文對基於電動力纜繩的航天器離軌過程進行了深入研究，具體工作如下:首先，本文研究了電動力纜繩產生電動力拉力的基本原理，建立了精確地磁場模型;分別在偶極子模型和精確地磁場模型作用下，對電動力拉力的大小、方向、離軌時間及電動力纜繩傾角的大小進行了計算分析;建立了電動力力矩與纜繩系統重力梯度力矩的平衡關系;分析了電動力力矩為系統提供能量的原理;最後分別在偶極子地磁場模型和精確地磁場模型作用下，對受電動力纜繩作用的航天器的離軌過程進行模擬，分析了在不同精度地磁場模型下，航天器離軌過程中各軌道參數的變化情況，並比較了不同模型對離軌時間的影響。 -
