Orbital Debris Removal Technologies: A Hybrid Electrodynamic Tether and Ion Beam Shepherd Satellite Design for Fuel Efficient Contactless Debris Removal
… as well as the expanding uses for earth-orbiting satellites. This thesis investigates the proposed technologies for the debris's removal both large and small. Focus is applied to the large debris removal technologies since the small size category is dominated by the ORION laser system. …

The user concept in the space industry and how this frames satellite missions, with a focus on social development in Africa
… because the conceptualisation of the user in the satellite industry is too narrow, and yet influences the architecture and thence outcomes of a satellite mission. Assumptions about users and markets are not made on the basis of data and market research, in itself typically difficult to obtain, …

Conceptual Phase Structural Design Tool for Microsatellites
Gaining traction or momentum in the conceptual design phase for a complex system can be an arduous and daunting process, whether the complex system being designed is a satellite, airplane, car, or one of countless other systems. The design of small satellites is particularly affected by the …

Investigating the Use of Biologically Inspired Design Tools in a Student CubeSat Design Team Through Workshop User Experiences
… investigates the role of Biologically Inspired Design (BID) in satellite engineering and examines how existing BID methods can be introduced into a student CubeSat design context. The study addresses three questions: the current extent of BID applications in satellite engineering, how BID tools …

An integrated evolutionary model approach to small satellite engineering
… the use of detailed integrated modeling in the design, fabrication, and operations of small satellites (<180kg). This need led to the design of the Integrated Evolutionary Model (IEM) approach to small satellite engineering. The IEM approach uses integrated modeling throughout the satellite …

Framework for evaluating customer value and the feasibility of servicing architectures for on-orbit satellite servicing
… examines is whether traditional monolithic satellite designs have limited the value that the satellite market generates for the space industry. To answer this question, this thesis focuses on the "Value" that satellites generate. By examining the value that satellites offer their operators, …

Development and analysis of a small satellite attitude determination and control system testbed
… Systems (ADCS) are critical to the operation of satellites that require attitude knowledge and/or attitude control to achieve mission success. Furthermore, ADCS systems only operate as designed in the reduced friction, micro-gravity environment of space. Simulating these characteristics of space …

Application of Bayesian-based uncertainty and global sensitivity analyses to spacecraft thermal design
As satellite design has increased in complexity, the evolution of thermal engineering of spacecraft has plateaued. For years, thermal engineers have used the same principles of designing to stacked worst case scenarios and applying additional margin on top of the already conservative predictions. …

Command and Data Handling-Driven Spacecraft Operations Using Hardware-in-the-Loop Simulation
… handing, and subsystem coordination. Traditional satellite evaluation methods often emphasize isolated subsystem validation or environmental simulation, while providing limited insight into end-to-end spacecraft operations governed by the Command and Data Handling (CandDH) subsystem. The thesis …

Adaptive and Responsive Design Under Uncertainty for Resource-Constrained Small Satellites
The space environment that satellites face is uncertain and challenging for survival and operation. Traditionally, satellite design methods mitigate the effects of uncertainty through the use of ample margin. However, robust designs often sacrifice significant nominal performance in exchange for …

Optimization and valuation of recongurable satellite constellations under uncertainty/
… strategy that utilizes on-demand, maneuverable satellites to provide focused regional coverage with short revisit times at greatly decreased cost when compared to traditional static satellite constellations. The thesis develops and demonstrates a general framework to guide the design and …

Maritime surveillance with small satellites
… for maritime safety. Monitoring AIS from the satellite close the gap between AIS that operate in coastal and open seas. However, the surveillance with satellite also has a limitation since AIS as a cooperative surveillance system tends to be switched off intentionally during illegal activities …

Space radiation environment impacts on high power amplifiers and solar cells on-board geostationary communications satellites
Communications satellite operators maintain archives of component telemetry to monitor system function. Operators generally do not typically use the telemetry data for scientific analysis of the space radiation environment effects on component anomalies or performance. We partnered with four …
