Numerical Optimization of Satellite Avoidance Maneuvers

2022-12-01 , Sheikh, Firas

This paper investigates the numerical optimization of a collision avoidance maneuver and phase return for a satellite in a constellation network. The time until collision and return time are varied, and three impulse maneuvers are assumed. The total Delta-V is minimized while avoiding the collision by 1 km or greater and returning to the original satellite orbit phase. For this analysis, the Clohessy-Wiltshire (CW) solutions were utilized to linearize the system of equations for relative orbital motion without perturbation assumptions. Results demonstrated that a greater time until collision generally produces minimized Delta-V options but longer total maneuver times as a tradeoff.

Integration and Testing of a 2U Cold-Gas Propulsion System for the SunRISE Mission

2022-08-01 , Shirazi, Kian E.

The Georgia Tech (GT) Space Systems Design Laboratory (SSDL) is building six identical cold-gas propulsion systems to provide the necessary maneuvering capabilities required by the SunRISE mission. The mission plans to observe low frequency emissions from the Sun by utilizing an array of CubeSats that will formation fly to create a large radio telescope in space. The cold-gas system design is based on the lab’s heritage design used for previous missions, namely BioSentinel, which leverages additive manufacturing to create a highly optimized propulsion system for the CubeSat form factor. The unique system consists of mainly a singular printed multifunctional structure encompassing tanks, plumbing, and nozzles, and utilizes a two-phase propellant to maximize the amount of propellant stored in the restricted volume and hence the total impulse provided by the system. This report provides a brief overview of the system design and its purpose in the SunRISE mission, while detailing the integration process and extensive testing campaign each flight unit goes through before they are delivered for integration with the spacecraft.

Urban Design Studio: Habersham County Growth Management and Conservation Strategies

2022-12 , Davis, Nathan , Davis, Madison , Scott, Sierra , Kaufman, Mira , Raven, Roxanne , Beduhn, Lauren

Georgia's land cover change over the past 50 years has been documented in an unprecedented study conducted by the Georgia Conservancy and the Georgia Tech Center for Spatial Planning and Visualization (CSPAV). This study has resulted in Georgia Now and Forever initiative, an ambitious undertaking to educate key decision-makers across Georgia as to the study's findings with a message that intentional, thoughtful decisions around the use of Georgia's remaining undeveloped land are inextricably linked to Georgia's future ecological and economic sustainability. item_description: Georgia's land cover change over the past 50 years has been documented in an unprecedented study conducted by the Georgia Conservancy and the Georgia Tech Center for Spatial Planning and Visualization (CSPAV). This study has resulted in Georgia Now and Forever initiative, an ambitious undertaking to educate key decision-makers across Georgia as to the study's findings with a message that intentional, thoughtful decisions around use of Georgia's remaining undeveloped land are inextricably linked to Georgia's future ecological and economic sustainability. Unsurprisingly, but important to have clearly documented, is the role low density development has played in the significant acreage conversion from agricultural land, forested land, and wetlands. These findings from past development patterns have allowed for the identification of plausible future landcover change trends, assuming business-as-usual development approaches. North Georgia is clearly in the path of major landcover change to low density developed land as metro Atlanta proceeds to "move" northward. This is also an area of significant ecological and carbon assets in the form of our mountain and valley forests, as well as agricultural lands. There is keen community interest in welcoming development-especially diverse and affordable housing choices-but alongside serious advancement in the conservation of the natural landscape. Representatives from the Habersham County, the City of Clarkesville and the property manager of a large conservation tract in the area that includes two riverfront miles of the Soquee River requested assistance from the Georgia Conservancy and Georgia Tech to consider how and where development and conservation can and should occur across their home county of Habersham. There is an understanding among this group that the very conditions that draw new residents to the area-the forests, mountains, streams-are at risk without a concerted effort to include conservation alongside land-efficient development. Given the larger situation in Georgia, the public and political will in the Clarkesville/Habersham area to pursue a larger joint development and conservation priority led to this planning process of identifying strategies for managing local resources in a sustainable way.

Urban Design Studio: Faith Based Affordable Housing

2022-12 , Delargy, Colin , Cena, Kortney , McFarlane, Clifton , Dominguez, Miriam , Waheed, Jullanar , Murphy, Ansley

Well known by now, and getting worse by the moment, is Atlanta’s affordable housing crisis. In the Atlanta case, as in “hot” markets all over the country, jurisdictions are trying to come up with strategies that might work. One such tried here and in other cities is to eliminate single family zoning. Early evidence in its usefulness for addressing affordability from Minneapolis, Seattle, and Portland, however, shows that strategy to be failing. It’s not producing density, the investment required is raising property values and taxes, the red hot “build to rent” markets are displacing neighborhoods, particularly Bipoc and low wealth neighborhoods. And its top-down approach is stripping communities of any input into the process. In short, this solutionist strategy does not work. In Atlanta, the city council decisively defeated it in December. item_description: Well known by now, and getting worse by the moment, is Atlanta’s affordable housing crisis. In the Atlanta case, as in “hot” markets all over the country, jurisdictions are trying to come up with strategies that might work. One such tried here and in other cities is to eliminate single family zoning. Early evidence in its usefulness for addressing affordability from Minneapolis, Seattle, and Portland, however, shows that strategy to be failing. It’s not producing density, the investment required is raising property values and taxes, the red hot “build to rent” markets are displacing neighborhoods, particularly Bipoc and low wealth neighborhoods. And its top-down approach is stripping communities of any input into the process. In short, this solutionist strategy does not work. In Atlanta, the city council decisively defeated it in December. Since we and others remain in a state of crisis, though, the context for this studio investigates strategies for what to do instead. These include coming up with the tools and resources to coordinate use of publicly and non-profit owned land; to maximize conservation of existing stock; and to concentrate densification in already dense areas like transit corridors and existing dense areas. For us, we will explore the potential for faith-based property owners to step up, using their land holdings as a way of underwriting the land cost element of an affordability-serving pro forma. This studio explores the issues and ideas from an overview perspective. The studio worked with four faith-based organizations to go deep, developing case studies to further tease out the issues and opportunities. This work was guided by these organizations, possible by nearby affected communities as well. The work product includes both our overview and the findings from the individual case studies. Students worked in group settings, applying their knowledge across the specializations of housing and community development, economic development, and urban design, along with associated regulatory and resource requirements. The studio progressed from data assembly to analysis, to consideration of alternatives, to suggested courses of action, to a final report and presentation. Stakeholder organizations will review each stage of the work. Students utilized their skills in data management, analysis, communication, and presentation in a cross-disciplinary and community engaged process.

Best Practices and Considerations for Planning and Conducting Integration of University CubeSats

2022-12-01 , Rawson, William

This paper seeks to serve as a resource for students entering the integration phase of a CubeSat project by compiling best practices and practical considerations from several projects in the Space Systems Design Lab at the Georgia Institute of Technology. The integration phase can be a particular challenge for university CubeSat programs given the value of practical experience in performing these activities and the challenge of managing a student workforce with constant turnover. The topics covered include best practices for planning the integration phase of a project, considerations when performing integration activities, and the characteristics of good assembly procedures. Although the focus is on spacecraft-level integration of CubeSats in a university setting, many of the considerations are applicable outside the academic setting and to subsystem-level integration activities as well. Finally, a case study will be presented illustrating the planning of integration activities for the VISORS mission, a two 6U CubeSat formation-flying mission

Urban Design Studio: Home Park Neighborhood Strategic Planning

2022-12 , Master, Michaela , Yohanis, Samrawit , Hudson, Joel , Noe, John , Lieu, Seung Jae , Neaves, Thomas , Yuxiang, Zhao , Rollins, Miles

Nestled between Georgia Tech and Atlantic Station (and between the Connector and Northside Drive), Home Park neighborhood leadership has provided planning frameworks through the years, ultimately approved and incorporated into the City of Atlanta’s own plans, that aim at maintaining neighborhood integrity and quality of life for its residents amidst change forces all around. This update will respond to these challenges by exploring their impact on neighborhood futures and also provide recommended short-term actions that signal reassertion or reimagining of neighborhood values. As such, students will be called upon to work in group settings, applying their knowledge across all specializations, emphasizing syntheses among them. The neighborhood will provide forums for reviewing and providing feedback to our progress and shaping these interests. Their organization is committed to carry out a long-term, inclusive, transparent, and community-engaged program. item_description: Nestled between Georgia Tech and Atlantic Station (and between the Connector and Northside Drive), Home Park neighborhood leadership has provided planning frameworks through the years, ultimately approved and incorporated into the City of Atlanta’s own plans, that aim at maintaining neighborhood integrity and quality of life for its residents amidst change forces all around.

The neighborhood will provide forums for reviewing and providing feedback to our progress and shaping these interests. Their organization is committed to carry out a long-term, inclusive, transparent, and community-engaged program. Examples of the neighborhood’s range of interests include; o Reviewing useful proposals from earlier planning work o Tackling housing-related issues like conservation, affordable housing options, and impacts of short-term rentals o Framing development options along corridors (10th Street, 14th Street, Hemphill, and Northside Drive), including traffic control options o Exploring urban design initiatives for strengthening neighborhood identity, ped/bike-oriented streetscape, and connectivity and SPI-8 parking priorities o Analyzing, as an empirical matter, how closely the City follows neighborhood master plans, with an eye towards strengthening the influence of those plans The studio work includes data assembly and analysis, the consideration of alternatives, suggested courses of action, and a final report and presentation. Community stakeholders were intimately involved in each stage of the work. As a framework planning/urban design exercise, the studio covered issues and opportunities across the full spectrum of planning specializations including: data collection, recordation, analysis, visualization and presentation in a cross-disciplinary and community involved processes, transportation planning, land use planning, open space planning, urban design and zoning.
