Application of orbital constraints for the photogrammetric processing of MOMS 3-Line Stereo Scanner Imagery (original) (raw)

Abstract

A new approach to photogrammetric restitution of 3-line stereo scanner images is presented for use within the MOMS-02 and MOMS-2P project. It is based on the replacement of the orientation image concept by a rigorous treatment of the orbit information in the bundle adjustment process. To this end, the trajectory data and the orbit determination parameter covariance matrix are incorporated into the photogrammetric processing, together with associated partial derivatives of the spacecraft position with respect to the epoch state and model parameters. By constraining the adjusted trajectory to the physical laws of orbital motion, the bundle adjustment process is stabilized by a significant reduction of the number of required destimation parameters. The basic algorithms for the incorporation of orbital constraints into the photometric evaluation of stereo scanner images and the resulting benefits are described. Special focus is given to the application for MOMS-02 image analysis and nec...
