A Sensitivity Analysis of Satellite Navigation Using Landmarks
Abstract
This work evaluates the sensitivity of satellite orbit determination using known landmarks to orbital altitude and imaging geometry. Known landmark-based orbit determination is an autonomous navigation technique that uses a satellite's optical observatory to image known landmarks. Measurements for orbit determination are generated by using image processing algorithms to find the location of known landmarks in each image. Previous work stretching back to the Apollo Program has shown landmark navigation to be feasible and evaluated its sensitivity to lighting, inclination, pointing accuracy, image resolution, and number of images collected. Evaluating sensitivity to altitude and imaging geometry is useful for selecting an orbit for the satellite and for tasking the satellite in order to maximize the information gained from each collected image.
