Traditional three line array stereoscopic mapping is constrainted by orbit determination precision, attitude determination and control precision. Compared with it, the line-matrix CCD array(LMCCD) camera structure can improve the global stereo mapping precision without ground control points(GCPs). The related subject in detail, which included sensor configuration of stereo mapping of LMCCD, TDI working mode, PCB connecting method in narrow space, time scale generation and LMCCD synchronous control was described. The tests indicate that the LMCCD mapping camera can effectively reduced orbit and attitude measurement error. It meets the requirements of 1:50 000 scale maps without GCPs, and the performance can be improved in future application.
