传统的无人机目标定位技术要求光电转台必须装配激光测距仪，因此光电转台至少是双装载。这使得转台体积和重量偏大，影响了飞机系统的续航时间、升限和时速，不适合挂装在小型无人机上。无人机航空吊舱采用惯导系统，GPS定位设备，舱体和光电转台固联的安装方式，消除了减振器带来的误差。对于平坦地势上的目标可以利用空间坐标系转换理论准确计算出目标在惯性空间中的三维坐标公式，同时结合飞机与地面的相对高度便可以算出飞机与目标点之间的斜距。再利用空间坐标变换的定位方法就能解算出目标 GPS坐标。这种方法不依赖激光测距机和无线电测高仪，单载荷的航空吊舱也能实现对平坦地势地面目标的准确定位。减少了吊舱的体积和重量，为提高飞机系统整体性能奠定了良好的基础。

Traditional UAS targeting technology needs optical turret load Laser Rangefinder. So optical turret must be double payload at least. This increases the turret volume and weight. Also the airplane’s fly time, altitude and speed are affected. So it doesn’t adapt to small UAS. INS, GPS, cabin and optical turret must be installed together in air pod and eliminates errors brought by shock absorber. We can calculate object’s three-dimensional coordinate formula using coordinate transformation theory. Combining the relative altitude of the plane to ground, we can calculate the side-glance distance of the plane and object. Finally we can calculate the object’s GPS coordinate. This method doesn’t depend on Laser Rangefinder and Wireless Height Equipment. Single payload air pod also achieve accurate target location. This reduces air pod’s volume and weight and establishes good base for enhancing plane holistic capability.
