Abstract

Direct space ground positioning system which is composed of Global Positioning System （GPS）

attitude measurement （i.e. inertial navigation system

INS） and laser scanning ranging is a new positioning technique developed in recent years

the system is one of the new methods which obtain geometric information of the terrain and generate digital elevation model for quantily of three dimensional remote sensing. This paper gives rigorous positioning equation and error transfer equation of air to ground positioning for airborne and space borne remote sensing. Error analysis of the system and precision evaluation based on the obtained equations for line scanning and circle scanning are given. The simulation computation indicates that the results of this paper have importance to practical application.
