摘要

这项研究介绍了卫星绕地球由于空气动力学力矩而产生的混沌振荡。卫星的轨道平面与地球的热带平面相同。利用Chirikov测度对混沌分界线的半宽进行了估计。各种边界技术表明，流线型的力边界、圆的不可预测性和质量比（ω0）将正常的摇摆转化为无组织的摇摆。我们用李雅普诺夫指数和时间序列图研究了由于参数变化而导致的轨迹行为。该理论应用于地球的人造卫星资源卫星1号。

Chaotic Oscillation of Satellite due to Aerodynamic Torque

This study presents the chaotic oscillation of the satellite around the Earth due to aerodynamic torque. The orbital plane of the satellite concurs is same as the tropical plane of Earth. The half-width of riotous separatrix is assessed utilizing Chirikov’s measure. Variety of boundary techniques shows that streamlined force boundary (ɛ), unpredictability of circle (e), and mass-proportion (ω0) convert normal wavering to the disorganized one. We studied the behavior of trajectories due to change in parameters with Lyapunov exponents and time series plots. The theory is applied to Resourcesat-1, an artificial satellite of the Earth.
