High-accuracy 3D image positioning is considered as the foundation of lunar topographic mapping.This study simulated the influence on image positioning from errors and correlations of Chang’e-1 optical sensor orientation elements

and established the rigorous block adjustment model suitable for lunar optical remote sensing images.The errors and area limits caused by the lunar curvature were avoided in this model established under the Selenocentric Orthogonal Coordinate System（SOCS）

the accidental errors of exterior line elements were reduced by orbit fitting and interpolation

the polynomial orders of systematic errors in satellite orbits were decreased with their expression in the flying coordinate system moving and rotating with satellites

and the reliability of exterior orientation solution was enhanced under the condition of sparse and low accuracy control points by appending constraint of orbit and attitude parameters.Finally

60 scenes of Clementine images near the south pole of the Moon were utilized in 10 strips with the area of around 195000km2 and ULCN2005 GCPs as the experimental data

and a series of helpful results was achieved on image positioning of the Moon.
