摘要
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。
Since Chang＇e-2 （CE-2） satellite entered the Lissajous orbit surrounding the Earth-Sun Lagrange point L2, the effect of jet uninstall was studied. A momentum management method by light pressure was given. The in orbit test shows that the Solar light pressure is strong enough to unload the momentum of CE-2 satellite, which is surrounding the L2 point. This method can substantially reduce the number of jet uninstall, and benefit the orbit maintenance of CE-2 satellite.
