A simulation study on point determination for the MOMS-02/D2 space project using an extended functional model (original) (raw)

In the course of the 2nd German Spacelab mission D2, scheduled for launch in 1993, the MOMS-02 camera is intended to acquire digital threefold stereo imagery of the earth's surface from space. In former simulations the influence of certain mission parameters on the attainable geometric accuracy has already been examined. With regard to the future compilation of real data, the functional model was extended with respect to the special MOMS-02 camera geometry and the actual orbit. After a brief description of the extended model, the results of new simulations are presented. They show the influence of the precision of observed exterior orientation parameters, the type and density of ground control, the camera inclination across flight direction and the simultaneous adjustment of two crossing strips with different intersection angles on the theoretical accuracy of the point determination. Because of the improved functional model the obtained accuracy estimates are expected to be repr...
