This paper focuses on the error characterization of spacecraft to achieve precision planetary landing using feature tracking through a sequence of descent images.Using matrix perturbation theory and covariance propagation, the error sensitivity of motion estimation with a general model of image noise is provided.The analyticity of our results allows us to examine the error sensitivity in terms of the translation direction, the viewing angle from the navigation camera.The motion estimation uncertainty is shown in the experimental results, leading to better use of the navigation method in engineering applications.
