摘要
Analysis methods for evaluating the maneuver capability in planetary terminal soft landing are researched based on the request of autonomous landing point redesignation. Firstly, to find out the relationship between acceleration model integral result and available velocity increment, a numerical method of maneuver capability analysis is deduced. Secondly, based on the assumption that counteracting the gravity effect and the position maneuver are two independent processes and the position maneuver is an ideal two-impulse maneuver, an analytic expression of maneuver capability analysis is proposed. Simulation result shows that the two methods can get similar results, and the analytic method can predict the potential landing point in real time, which plays an essential role in landing point redesignation.
