Characterization and Helicopter Flight Test of 3-D Imaging Flash LIDAR Technology for Safe, Autonomous, and Precise Planetary Landing
… and flight tested under the Autonomous Landing and Hazard Avoidance (ALHAT) project (in its fourth development and field test cycle) which is seeking to develop a guidance, navigation, and control (GNC) and sensing system based on lidar technology capable of enabling safe, precise …

A unified vision and inertial navigation system for planetary hoppers
… has been paid to hopping as a novel mode of planetary exploration. Hopping vehicles provide advantages over traditional surface exploration vehicles, such as wheeled rovers, by enabling in-situ measurements in otherwise inaccessible terrain. However, significant development over previously …

Outlier-Robust Multi-View Triangulation Using Graduated Non-Convexity for Space Vehicle Navigation
… ultimately estimate the spacecraft’s pose during planetary landing and navigation. This thesis seeks to improve current multi-view triangulation methods to optimally perform with an outlier-dominant (>50% outlier) dataset. Outlier-dominant situations may occur in cases of extreme environmental …

Enhancement of perception with the application of stochastic vestibular stimulation
… in a task relevant to piloting during planetary landing, docking, or other vehicle maneuvers. In a first experiment, upright roll tilt direction recognition thresholds, which elicit responses from both the semicircular canals and otoliths, were measured with varying levels of SVS …
