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.
对准过程分作二步完成，即解析对准与开环精对准。
The basic principles of system alignment are introduced. The realization methods of Coarse Alignment and Precision Alignment are discussed in detail.
本文研究了捷联式惯性导航系统初始对准的基本原理，讨论了粗对准阶段和精对准阶段的实现方法。
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.
针对这一问题，提出了利用惯性空间中地球重力加速度信息的捷联惯导自主粗对准方法，以及基于模糊自适应卡尔曼滤波的自主精对准方法。
