In astronomical coordinates ( reference mark is north latitude 43. 9 ), analyzed is the effect of azimuth angular velocity, acceleration and altitude angular velocity, acceleration etc. some formulae were given to compute all correlative quantities. with regard to the course of data processing beforehand, the thesis focuses on outliers eliminating technology because of outlier increasing acutely of high - elevation tracking ( approaches 10 - 20 % )
在觀測坐標系中推導出確定天頂盲區理論范圍公式和滿足過天項跟蹤條件的關系式；在天文坐標系中以長春衛星觀測站（北緯43 . 9 ）作為計算基準，分別討論了方位、俯仰方向的角速度、角加速度等對天頂盲區的影響，在理論分析上為解決過天頂跟蹤問題打下了基礎。 -
Spacecrafts are working in the space environment, which is full of sorts of physical mediums. and these mediums will impact on the altitude movement of spacecraft. spacecraft attitude control during propulsive maneuvers is complicated due to several factors as listed below : ( i ) nonlinear dynamics with time delays, ( ii ) modeling and parameter uncertainties, ( iii ) flexible modes due to fuel sloshing and appendages, ( vi ) constraints on propulsive force and torque inputs, ( v ) constraints on acceptable angular rates and attitude, ( iv ) autonomous reconfiguration requirements under failure conditions
飛行器是在一定的空間環境中飛行，而空間環境中充滿著各種物理介質，對飛行器的姿態運動產生不同程度的影響，所以空間飛行器的姿態控制相當復雜，它受到如下因素的制約： （ ? ）帶時延的非線性動態特性（ ? ）模型和參數的不確定性（ ? ）燃料的激蕩性以及燃料消耗所引起飛行器的質量變化（ ? ）推力和輸入力矩的約束性（ ? ）額定角速度約束和姿態約束（ ? ）在故障發生的情況下自動重新配置的必要性。
