Abstract: In order to accurately evaluate the agility satellite effectiveness and set the reasonable indices of maneuvering ability and measuring component,the influence on the stereo position accuracy was compared between the satellite with single-linear-array CCD camera(SLAC) and the one with three-linear-array, based on the agility satellite mapping synchronously during the maneuvering.The agility satellite stereo mapping position accuracy evolution model was established.The approximate analytic algorithm of the errors were given according to the correlation between the inner and outer elements with angular orientation elements. Mathematical calculation shows that the indices of the agility satellite stereo mapping angle elements and measurement accuracy meet the requirements of the position accuracy.

Key words: Stereo mapping, Single-linear-array charge coupled device camera, Position accuracy assessment model, Agility satellite
