Powered Descent Trajectory Guidance and Some Considerations for Human Lunar Landing

摘要: The Autonomous Precision Landing and Hazard Detection Avoidance Technology development (ALHAT) will enable an accurate (better than 100m) landing on the lunar surface. This technology also permit autonomous (independent from ground) avoidance of hazards detected in real time. A preliminary trajectory guidance algorithm capable supporting these tasks has been developed demonstrated simulations. Early results suggest that with expected improvements sensor mapping, mission objectives are achievable.
