Guidance and Control Design for Powered Descent and Landing on Mars

摘要: Future Mars landing missions must be capable of autonomously delivering highly and mobile rovers safely gently in an upright orientation. The airbag system used to deliver earlier (Mars Pathfinder the two Exploration vehicles) is incapable Science Laboratory (MSL)-class rover. design a novel sky-crane concept land proposed rover presented here. descent guided actively controlled six degrees freedom. Terminal guidance robust terrain variations-induced altimeter noise. A terminal sensor provides surface relative velocity altitude measurements, inertial measurement unit measurements help propagate vehicle attitude positions. Guidance control commands eight throttle-able lander engines translations. Computer simulations demonstrate viability this presence various environmental, configuration, hardware imperfections.
