New numerical method improving the integration of time in KS regularization

an orbiter as a reference to generate a line of sight to the landing location. By utilizing already existing visual sensors on the orbiter, the lander can be equipped with relatively simple radar sensors for slant range and slant range-rate measurements. Lastly, although the method has been considered for soft landing of payloads, it may, in principle, be used for accurate targeting of impacting penetrators during hyperbolic fly pasts.
