无人机空中光轴基准安装误差及磁偏差测量方法研究

Installtion Errors and Magnetic Deviation Measuring & Correcting Based on Optical Axis

测定飞机与目标定位有关的机载设备的安装误差、磁偏角等固定误差,是无人机实际目标定位前必做的一项工作。现有测定、校正方法繁琐且实用性差。给出一种不同于现有工序,在无人机空中实际目标定位前,在空中利用飞行器本身光电平台的光轴作为基准,对预先测定好经纬度的地面目标进行定位,反向推算来测量出飞机的固定安装误差及磁偏角,再进行校正的方法。该方法具有工序简单、精度高、实用的特点,有较大的实际应用价值。

Measuring the unchangged errors, including installtion errors and magnetic deviation is a necessary process before actually target location of UAV. This paper makes a probe unlike the existing process about installtion errors and magnetic deviation measuring and correcting using aircraft itself optical axis of optical platform as reference in the air. The method is of simple process, high precisionfeatures, and has a greater practical value.
