AI Technical Summary

Technical Problem

The initial attitude verification of an aircraft before launch relies on external equipment, which is costly and risky. Existing methods are complex to operate and easily affected by the external environment.

Method used

By utilizing the aircraft's own inertial navigation system, the attitude is updated and accuracy is verified by calculating the pitch and roll angles of the aircraft from the accelerometer outputs, and then using the quaternion method and differential solution method. This includes multiple calculations and comparisons of attitude angles in both horizontal and vertical states to achieve autonomous verification.

Benefits of technology

It eliminates the need for external equipment, reducing costs and risks, simplifying operations, and improving the accuracy and efficiency of verification.

Abstract

一种飞行器初始姿态校核方法、装置、设备及可读存储介质,飞行器初始姿态校核方法包括:在飞行器起竖过程中,基于飞行器的第一俯仰角、第一滚转角及第一航向角对飞行器的姿态进行持续更新,计算飞行器起竖完成后处于竖直状态时的第二俯仰角、第二滚转角及第二航向角;在飞行器处于竖直状态时,计算得到飞行器的第三俯仰角和第三航向角;将惯性导航系统再次执行自动对准指令后输出的航向角作为飞行器的第三滚转角;通过将飞行器的第二俯仰角、第二滚转角及第二航向角,与第三俯仰角、第三滚转角及第三航向角分别进行对比,对飞行器的初始姿态进行精度校核。通过本申请,飞行器初始姿态的精度校核无需依赖外部设备,降低了成本及外部设备风险。
