对“嫦娥二号”(CE-2)卫星进入环绕日地拉格朗日L2点的李萨如轨道后卫星喷气卸载所产生的影响进行了研究。提出了一种利用光压力矩辅助卫星太阳电池翼角度调整进行角动量管理的方法。在轨试验表明,太阳光压强度足够对飞行在L2点环绕轨道上的CE-2卫星进行角动量管理,可以大幅度减少动量轮在轨喷气卸载的次数,有利于CE-2卫星的轨道维持。
The impact of the LESAR orbital satellite jet unloading on the Chang-2 (CE-2) satellite entering the Lagrangian L2 at orbit around the Earth was studied. A method of using angular moment to assist the angle adjustment of satellite solar cell to carry out angular momentum management is proposed. In-orbit tests show that the sufficient solar pressure to perform angular momentum management on CE-2 satellites orbiting the L2 orbital can significantly reduce the number of in-orbit jet unloading carried by the momentum wheel and contribute to the orbit maintenance of the CE-2 satellite .
