| 摘 要： | 为了得到侦察目标的大地坐标以及引导载机捕捉已知目标,提出了机载GPS测量定位方法.应用GPS技术,获取载机及已知目标的位置信息,利用齐次坐标转换方法进行定位引导过程的坐标转换,从而得到目标定位引导数据.通过实验对机载GPS测量定位方法进行了检验.实验结果表明:定位精度达到了30 m,引导精度为2°.用蒙特卡洛法对实验误差进行了分析并得到了精度误差范围,其结果在期望的误差范围内,表明机载GPS测量定位技术具有一定的实用和推广价值.

| Abstract: | In order to get geodetic coordinate and guide an aircraft to capture target,a measuring orientation method is proposed to obtain the location coordinates of aircraft and known target by GPS technology.Then,a homogeneous coordinate transformation method is used to transform coordinate in orientation guide process to obtain the target data of orientation guide process.The measuring orientation technology based on airbone GPS is validated by the experiment,the result shows that the position accuracy is 30 m,an... |
