摘　　要：主要介绍了通过对GPS差分数据进行无控制点或少控制点的内业空三解算结果的分析得出,基于GPS差分技术的无控制或少控制航空摄影测量的精度完全可以满足航摄测图的精度要求。Fewer GPS needs to be surveyed if GPS is used with digital camera in photogram- merry. In this paper, GPS--supported aerial triangulation measurement accuracy against the number of ground control points were investigated. A set of actual aerial photos with GPS camera position data taken from Badaling of Beijing were used. The test was done by the use of software PBBA developed by Beijing geo--vision tech Co. ,Ltd. By analyzing of Aerial photogrammetry precision of no control points or less control based on GPS differential technology we will know that it can satisfy photographic measurement accuracy.
