The intuitive interaction capabilities of augmented reality make it ideal for solving complex 3D problems that require complex spatial representations, which is key for astrodynamics and space mission planning. By implementing common and complex orbital mechanics algorithms in augmented reality, a hands-on method for designing orbit solutions and spacecraft missions is created. This effort explores the aforementioned implementation with the Microsoft Hololens 2 as well as its applications in industry and academia. Furthermore, a human-centered design process and study are utilized to ensure the tool is user-friendly while maintaining accuracy and applicability to higher-fidelity problems.

Evaluating The Effectiveness Of Game-Based Virtual Reality In Satellite Ground Control Operations Education And Training, Lana Laskey, Joseph R. Keebler, Paul M. Cairns, Geovanny Lopez
International Journal of Aviation, Aeronautics, and Aerospace
There is increased global demand for satellite amenities such as navigation, communications, weather reporting, disaster management, agricultural operations, or humanitarian assistance. The growing demand for satellite technology amplifies the need for highly trained satellite operators. Traditional simulation training methods typically utilize two-dimensional computer displays. However, training approaches involving game-based instruction and immersive virtual reality have shown benefits when integrated with complex disciplines and may provide an advanced training alternative for satellite operators. Game-based instruction enhances user motivation and cognitive engagement, while immersive virtual reality promotes user presence and prolonged cognitive engagement. The combination of these two training methods, noted as …
Deep-Learning Based Multiple-Model Bayesian Architecture For Spacecraft Fault Estimation, 2023 Embry-Riddle Aeronautical University
Deep-Learning Based Multiple-Model Bayesian Architecture For Spacecraft Fault Estimation, Rocio Jado Puente
Doctoral Dissertations and Master's Theses
This thesis presents recent findings regarding the performance of an intelligent architecture designed for spacecraft fault estimation. The approach incorporates a collection of systematically organized autoencoders within a Bayesian framework, enabling early detection and classification of various spacecraft faults such as reaction-wheel damage, sensor faults, and power system degradation.
To assess the effectiveness of this architecture, a range of performance metrics is employed. Through extensive numerical simulations and in-lab experimental testing utilizing a dedicated spacecraft testbed, the capabilities and accuracy of the proposed intelligent architecture are analyzed. These evaluations provide valuable insights into the architecture's ability to detect and classify …
Accelerating Machine Learning Inference For Satellite Component Feature Extraction Using Fpgas., 2023 Florida Institute of Technology
Accelerating Machine Learning Inference For Satellite Component Feature Extraction Using Fpgas., Andrew Ekblad
Theses and Dissertations
Running computer vision algorithms requires complex devices with lots of computing power, these types of devices are not well suited for space deployment. The harsh radiation environment and limited power budgets have hindered the ability of running advanced computer vision algorithms in space. This problem makes running an on-orbit servicing detection algorithm very difficult. This work proposes using a low powered FPGA to accelerate the computer vision algorithms that enable satellite component feature extraction. This work uses AMD/Xilinx’s Zynq SoC and DPU IP to run model inference. Experiments in this work centered around improving model post processing by creating implementations …
Experiments And Simulations Of Liquid Mass Gauging And Slosh Dynamics In Microgravity, 2023 Florida Institute ofTechnology
Experiments And Simulations Of Liquid Mass Gauging And Slosh Dynamics In Microgravity, Jedediah Morse Storey
Theses and Dissertations
Advancements in liquid propellant management science and technologies are key to increasing safety, decreasing cost, and increasing payload mass of space missions. Propellant usually comprises a large portion of the total mass of launch vehicles and spacecraft, so liquid propellant sensing, as well as predicting and controlling the motion of it, are important. Electrical Capacitance Tomography (ECT) is an emerging sensing technology that is capable of measuring the distribution of liquid anywhere inside of a tank, potentially making it useful for measuring slosh and gauging mass. An ECT-instrumented tank was successfully tested in microgravity for the first time. Basics of …
Analysis Of An Electrospray Thruster With A Concave Propellant Meniscus, 2023 University of Tennessee, Knoxville
Analysis Of An Electrospray Thruster With A Concave Propellant Meniscus, Adam Nicholas Huller
Masters Theses
The low thrust, high specific impulse, and low mass of electrospray thrusters (ETs) make them ideal for maneuvering nanosatellites, especially with the new requirement to deorbit a satellite within five years of completing its mission. These innovative thrusters use electrohydrodynamic principles of electrospray (ES) to provide thrust. These principles have been subject to much research over the past decade, though much more research is needed to fully understand the underlying physics of these thrusters. The first part of this study establishes a procedure for analyzing the theoretical thrust performance of an ET, by using propellant properties and well-documented ES scaling …
Launch Vibration Attenuation For In-Space Assembly Cargo, 2023 California Polytechnic State University, San Luis Obispo
Launch Vibration Attenuation For In-Space Assembly Cargo, Jered Bell
Master's Theses
This thesis investigates the implementation of a passive isolator with a pressurized air cushion for spacecraft payloads in mission architectures implementing in-space assembly technologies. A pressurized air bed capable of briefly surviving the space environment for cargo delivery was prototyped and experimentally evaluated for launch vehicle vibration dynamics resulting in a 72%, 93%, and 88% reduction in experienced GRMS loads for the X-Axis, Y-Axis, and Z-Axis, respectively. A preliminary Total Mass Loss evaluation of the Low-Density Polyethylene Film utilized for the air bed resulted in a mass loss of 0.7%, indicating that commercial off-the-shelf films might require minimal modification for …

The Spacepower Theory Project seeks to gain insight into human behavior in outer space. The project’s overall objective is to develop a theoretical framework that helps to define, categorize, explain and anticipate ways in which “spacepower” may be pursued, how the various facets of spacepower connect to each other, and how they relate to the other instrumentalities of power that state and non-state actors may seek to achieve or retain.

The case of export controls of United States (U.S.) commercial satellites is characterized by bureaucratic politics leading to policy outcomes that are not rational, i.e., the desired outcome of national security is not met and commerce in the satellite sector is harmed. The constraints to rational policy making are a result of competition, conflict, and protectionism, the “bureaucratic politics,” among the relevant actors including the U.S. President and Congress, Department of State (State), Department of Commerce (Commerce), and Department of Defense (DOD). It is bureaucratic politics that result in policies for licensing the export of commercial satellites that are far …

The American Bubble: International Traffic In Arms Regulations And Space Commerce, Roger Handberg
Space and Defense
International space commerce in the United States (U.S.) has entered into a period of great uncertainty regarding its current and future competitiveness and marketability of its products. This question arises because the U.S. with regard to space commerce remains frozen in a posture established first during the Cold War. The concern then was that no critical technologies be made available to U.S. enemies and their fellow travelers. The former were obvious while the latter were more problematic since that group also included states with which the U.S. wished to establish more positive relations including international trade. The mechanism used to …

All nations regulate Arms sales, but the United States (U.S.) has traditionally gone further than most. After World War I, a conspiracy theory made its way into popular culture that blamed the war, and specifically the U.S. intervention in 1917, on the so called “merchants of death.” Ever since, this has been a powerful and enduring theme in politics and culture throughout the world. Yet, nowhere have the effects of this theory been more enduring than in U.S. policy and law.
