coarse alignment

基本解释

The alignment process is separated into two steps, i. e. , coarse alignment, or analytical alignment, and open-loop fine alignment.
對準過程分作二步完成，即解析對準與開環精對準。
The basic principles of system alignment are introduced. The realization methods of Coarse Alignment and Precision Alignment are discussed in detail.
本文研究了捷聯式慣性導航系統初始對準的基本原理，討論了粗對準堦段和精對準堦段的實現方法。
The paper proposes a new alignment scheme, in which the gravity message is used in the coarse alignment procedure, and an adaptive Kalman filter is used in the fine alignment procedure.
針對這一問題，提出了利用慣性空間中地球重力加速度信息的捷聯慣導自主粗對準方法，以及基於模糊自適應卡爾曼濾波的自主精對準方法。
