A Systems Margin Metric for Capability Above Basic Estimates
Jan 3, 2022
Price, Hoppy; Lepsch, Roger, 2022, "A Systems Margin Metric for Capability Above Basic Estimates", https://hdl.handle.net/2014/56102, AIAA SciTech 2022, San Diego, California, January 3-7, 2022, JPL Open Repository
A systems margin metric is described that indicates the total system performance capability above the basic estimates (CABE) for mass, power, energy, propellant, V, ISP, computer performance, and any other design parameter with a defined margin. This concept normalizes all terms...
Design of Flexures for Deployable Reflectarrays Using High Strain Composites
Jan 3, 2022
Dharmadasa, Yasara B.; Mejia-Ariza, Juan; Arya, Manan; Sauder, Jonathan; Focardi, Paolo; Case Bradford, Samuel; López Jiménez, Francisco, 2022, "Design of Flexures for Deployable Reflectarrays Using High Strain Composites", https://hdl.handle.net/2014/56114, AIAA SciTech 2022, San Diego, California, January 3-7, 2022, JPL Open Repository
This paper presents a novel flexure design for small scale refelectarrays, specifically CubeSats, that requires high level of deployment precision. Advantages of using a HSC flexure includes additional thermal stability, lesser part count and passive deployment mechanism using th...

Camera Simulation for the Perseverance Rover’s Lander Vision System
Jan 3, 2022
Aaron, Seth; Cheng, Yang; Trawny, Nikolas; Mohan, Swati; Montgomery, James; Ansari, Homayoon; Smith, Ken; Johnson, Andrew; Goguen, Jay; Zheng, Jason, 2022, "Camera Simulation for the Perseverance Rover’s Lander Vision System", https://hdl.handle.net/2014/56110, AIAA SciTech 2022, San Diego, California, January 3-7, 2022, JPL Open Repository
On February 18, 2021, the Perseverance Rover safely landed on Mars at Jezero Crater. Part of the successful landing was due to the Lander Vision System (LVS), which takes descent images from the LVS Camera (LCAM) and IMU measurements and estimates the lander position relative to...
