The invention discloses a stability augmentation layout of an ultra-low earth orbit satellite. The stability augmentation layout comprises an ultra-low earth orbit satellite body, a set of sweepback solar cell wings and a set of sweepback side plates. A body of the ultra-low orbit satellite is of an octagonal prism structure with a regular octagonal cross section, an equipment filling space can be provided, the solar cell piece distribution requirement can be met, a set of solar cell wings are located on the two sides of the ultra-low orbit satellite body respectively, and a set of side plates are located at the tail ends of the solar cell wings and are perpendicular to the solar cell wings. The method is used for passive control of the ultra-low orbit satellite attitude. The stability augmentation layout designed by the invention can effectively reduce the rolling torque of the ultra-low earth orbit satellite when the ultra-low earth orbit satellite runs in the deep atmosphere, reduce the influence of the rarefied atmosphere in the deep atmosphere on the running orbit of the ultra-low earth orbit satellite, contribute to improving the attitude control of the ultra-low earth orbit satellite, and improve the running stability of the ultra-low earth orbit satellite.
本发明公开了一种超低轨卫星的增稳布局,包括超低轨卫星本体、一组后掠太阳电池翼和一组后掠侧板。所述超低轨卫星的本体为截面正八边形的八棱柱结构,可以提供设备装填空间和太阳电池片布片要求,一组太阳电池翼分别位于超低轨卫星本体的两侧,一组侧板位于太阳电池翼尾端并与太阳电池翼垂直,用于超低轨卫星姿态的被动控制。本发明所设计的增稳布局可有效减小超低轨卫星在深层大气层运行时的滚转力矩,降低深层大气层中的稀薄大气对超低轨卫星运行轨道的影响,有助于改善超低轨卫星的姿态控制,提高超低轨卫星的运行稳定性。
