early-warning distance
解釋
預警距離-
By means of the orbit dynamics theory and other knowledge, author established mathematical model related to collision forecast, including space object orbit confirming model, space objects relative movement model, dangerous object distinguishing model and space object collision geometry relation model, etc. according to the mathematic model, author calculated the relative distance transformation rule along with time between the spacecraft and dangerous debris and established early warning rule
依據航天動力學理論和其他知識,建立了碰撞預警相關的數學模型,包括空間目標軌道確定數學模型、空間物體相對運動數學模型、危險物體判定準則數學模型和空間物體碰撞幾何關系數學模型等,根據數學模型計算航天器和危險目標的相對距離隨時間變化規律,設定了預警規則。
