dynamic orbit determination

基本解释

On the other hand, the precision gravity model is important guarantees for obtaining high precision orbiting results using the dynamic or reduced-dynamic orbit determination method.
低轨重力卫星轨道的精确确定是获得精密地球重力场模型的前提，而精密重力场模型又是获得高精度定轨结果的保证。
It is concluded that for the lunar missions not aiming at improving lunar gravity, such as the 'Chang Er 1', the reduced dynamic method of orbit determination is effective in absorbing gravity errors.
结果表明对于一个不将月球重力场作为主要科学目标的探月计划（如“嫦娥1号”），减缩动力学方法是一个简单、有效地提高环月飞行器定轨精度的方法。
