Quasi Real-Time Autonomous Satellite Detection and Orbit Estimation
Jarred Jordan, Daniel Posada, Matthew Gillette +2
A method of near real-time detection and tracking of resident space objects (RSOs) using a convolutional neural network (CNN) and linear quadratic estimator (LQE) is proposed. Adva…
Autonomous Local Catalog Maintenance of Close Proximity Satellite Systems on Closed Natural Motion Trajectories
Christopher W. Hays, Kristina Miller, Alexander Soderlund +2
To enable space mission sets like on-orbit servicing and manufacturing, agents in close proximity maybe operating too close to yield resolved localization solutions to operators fr…
Orbital Acceleration Using Product of Exponentials
Taylor Yow, Christopher W. Hays, Aryslan Malik +1
The Product of Exponentials (PoE) formulation is most commonly used in the field of robotics, but has recently been adapted for use in describing orbital motion. The PoE formula fo…
Initial Orbit Determination for the CR3BP using Particle Swarm Optimization
David Zuehlke, Taylor Yow, Daniel Posada +4
This work utilizes a particle swarm optimizer (PSO) for initial orbit determination for a chief and deputy scenario in the circular restricted three-body problem (CR3BP). The PSO i…
RGB-D Robotic Pose Estimation For a Servicing Robotic Arm
Jared Herron, Daniel Lopez, Jarred Jordan +5
A large number of robotic and human-assisted missions to the Moon and Mars are forecast. NASA's efforts to learn about the geology and makeup of these celestial bodies rely heavily…
Detection and Initial Assessment of Lunar Landing Sites Using Neural Networks
Daniel Posada, Jarred Jordan, Angelica Radulovic +3
Robotic and human lunar landings are a focus of future NASA missions. Precision landing capabilities are vital to guarantee the success of the mission, and the safety of the lander…
Satellite Detection in Unresolved Space Imagery for Space Domain Awareness Using Neural Networks
Jarred Jordan, Daniel Posada, David Zuehlke +3
This work utilizes a MobileNetV2 Convolutional Neural Network (CNN) for fast, mobile detection of satellites, and rejection of stars, in cluttered unresolved space imagery. First,…
Autonomous Satellite Detection and Tracking using Optical Flow
David Zuehlke, Daniel Posada, Madhur Tiwari +1
In this paper, an autonomous method of satellite detection and tracking in images is implemented using optical flow. Optical flow is used to estimate the image velocities of detect…
NASA/GSFC's Flight Software Core Flight System Implementation For A Lunar Surface Imaging Mission
Mohammed Eleffendi, Daniel Posada, M. Ilhan Akbas +1
The interest in returning to the Moon for research and exploration has increased as new tipping point technologies are providing the possibility to do so. One of these initiatives…
Hazard Detection And Avoidance For The Nova-C Lander
Joel Getchius, Devin Renshaw, Daniel Posada +4
In early 2022, Intuitive Machines' NOVA-C Lander will touch down on the lunar surface becoming the first commercial endeavor to visit a celestial body. NOVA-C will deliver six payl…
Modeling of an On-Orbit Maintenance Robotic Arm Test-Bed
Jacob J. Korczyk, Daniel Posada, Aryslan Malik +1
This paper focuses on the development of a ground-based test-bed to analyze the complexities of contact dynamics between multibody systems in space. The test-bed consists of an air…
Structural Design and Impact Analysis of a 1.5U CubeSat on the Lunar Surface
Christopher W. Hays, Daniel Posada, Aryslan Malik +3
Ahead of the United States' crewed return to the moon in 2024, Intuitive Machines, under a NASA Commercial Lunar Payload Services contract, will land their Nova-C lunar lander in O…
Using Products of Exponentials to Define (Draw) Orbits and More
Aryslan Malik, Troy Henderson, Richard Prazenica
The Product of Exponentials (PoE) formula is a mathematical tool that is used extensively in robotics. The virtue of using the exponential mapping, Lie Algebra and screw theory is…
