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.
低軌重力衛星軌道的精確確定是獲得精密地球重力場模型的前提，而精密重力場模型又是獲得高精度定軌結果的保証。
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.
結果表明對於一個不將月球重力場作爲主要科學目標的探月計劃（如“嫦娥1號”），減縮動力學方法是一個簡單、有傚地提高環月飛行器定軌精度的方法。
