Abstract

The different mapping systems is analyzed in this paper, and as a way of acquiring elevation with high accuracy and effectiveness, laser altimeter can improve the capability of 3- dimensional earth observation of satellite optical remote sensing imagery. And using high accuracy elevation observation of space-borne laser altimeter as control points accords with the trend of satellite photogrammetric without ground control points. In this paper, the problems of satellite photogrammetric are firstly introduced, and then the method of space-borne laser altimeter supported aero triangulation is described, which can solve these problems due to the characteristics of laser altimeter. The bundle adjustment error equations are established according to the earth observation of satellite image and space-borne laser altimeter, as well as the relationship of their exterior orientation elements. Elevation observations supplied by laser altimeter can be used as elevation control points to improve the accuracy of aero triangulation and the positioning accuracy. Finally, the improvement of elevation accuracy is shown by simulation using aero triangulation experiment of satellite image and space-borne laser altimeter, which can be improved from 9m to 1.6m.
