Abstract: On board information fusion for multi satellite which is based on spatial computing mode can improve the satellitescapability such as the accuracy of detection, the confidence of recognition, the precision of position and the coverage of spatial temporal for disaster monitoring, maritime surveillance and other emergent or continuous persistent observing situations. Firstly, the necessity of on board information fusion is analyzed. Secondly, the on board processing developments are summarized and the existing problems are discussed. And thirdly, the key technology and concepts of on board information fusion are studied in the fields of target feature representation, target association, feature level fusion, autonomous mission planning and other issues. Finally the future developments of on board information fusion are studied and discussed.

Key words: On board processing, Information fusion, Space information network, Spatial computing
