Abstract：In view of the problem of the precision of line elements of exterior orientation for miniature UAV remote sensing system that is not high,differential GNSS method is provided to improve solution of UAV remotr sensing system.Firstly,the accuracy of track record is improved by differential GNSS technology.Then,the camera delay correction is used for obtain the real time of camera flash.Thus,high precision line elements of exterior orientation can be obtained by interpolating in the track.Aerial triangulation with measure data shows the method can improve the precision of line elements of exterior orientation to sub-meter.
