Abstract

The article is devoted to deriving reference models for the problem of initial alignment of a strapdown inertial navigation system (INS) on a swing base. It is assumed that the system does not move relative to the Earth, but its body can make uncontrolled angular motions. The described models are based on the approximation of the readings of INS accelerometers from projections on the axes of the instrument reference frame ‘‘frozen’’ in the inertial space, and the orientation of the frame is determined by its position at the start of the alignment.

摆动底座捷联式惯性导航系统的初始对准方法

摘要

本文致力于为摆动底座上捷联惯导系统 (INS) 的初始对准问题推导参考模型。假设该系统不相对于地球移动，但它的身体可以做出不受控制的角运动。所描述的模型基于惯性空间中“冻结”的仪器参考框架轴上投影的 INS 加速度计读数的近似值，并且框架的方向由其在开始时的位置确定结盟。
