Abstract

fetched live from OpenAlex

Future planetary exploration missions will aim at landing a spacecraft in hazardous regions of a planet, thereby requiring the ability to autonomously perform the critical landing operations, including the avoidance of surface obstacles and the identification of the best landing site. These algorithms are rather complex and cannot be tested easily at moderate cost on a real system. Therefore, closed-loop software simulator tools are required to validate these new technologies, generate new advancements and help plan for future planetary exploration missions. This paper presents a closed-loop planetary landing simulator and its use in the validation of the hazard-avoidance landing technologies. The simulator emulates the real world with a 7-degree-offreedom landing dynamics, models of sensors and actuators and it closes the control loop with the on-board software that provides the “intelligence” to the landing vehicle. The paper will provide an overview of the Lidar-based guidance, navigation and control functions and it will demonstrate their successful validation through Monte Carlo simulations using the simulator adapted to a Mars landing mission.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
