| 摘 要： | 描述了一种用于桅杆式光电系统的侦察定位方法，采用单一陀螺和双轴倾角传感器组合，替代三轴正交的陀螺仪，对光电设备进行姿态测量；结合惯性导航设备获得的大地北向、激光测距机获得的目标相对距离、卫星定位设备获得的本地坐标，通过坐标系转换，能够准确获得目标的大地坐标。试验结果表明:通过该方法获得的系统定向精度达到0.3 mil，目标的定位精度优于10 m(CEP)。

| Abstract: | A reconnaissance orientating method for mast-mounted photoelectric system was described. Single gyro and a double-axis inclinometer were utilized to substitute for a tri-axis perpendicular gyro, to measure the attitude of the photoelectric equipment. Combined with the earth north orientation by inertial navigation equipment, the relative distance between object and equipment obtained by laser range finder, and the native geodetic coordinate obtained by satellite positioning, the geodetic coordinate of object could be acquired accurately by coordinate transformation.The examination results show that the system orientation accuracy can reach 0.3 mil, and the object positioning accuracy can excel 10 m(CEP). |
