摘要
GPS投入使用以来,其相对定位技术得以快速发展,GPS精密单点定位技术(PPP)的出现,极大地提高了工作效率。该技术可以达到分米甚至厘米级精度,可满足1∶5 000,1∶10 000及以上比例尺航测成图像片控制点精度要求。本文以宝清县测区1∶10 000比例尺为例,介绍GPS精密单点定位技术(PPP)在像片控制测量中的应用。
GPS has been widely applied for its technology of relative positioning. The emergence of PPP greatly improves the efficiency and has the accuracy of centimeter, which meets the requirements of aerial image control point of 1:5 000 and 1:10 000. The paper takes Baoqing country of 1:10 000 as the example to introduces GPS precise point positioning in the image control measurement.
