Spectre – Design of a Bimodal Propulsion System

2021-12-01 , Colon, Brandon J.

Miniaturization of propulsion systems has pushed the capabilities of small satellites by allowing them to perform more complex tasks such as orbital maneuvers and formation flying. Georgia Institute of Technology’s Space Systems Design Lab (SSDL) is designing a dual-mode propulsion system referred to as Spectre which will utilize AF-M315E (ASCENT) monopropellant to feed both modes. The propulsion system is capable of performing high thrust maneuvers via a chemical thruster that provides 1 N of thrust force and high efficiency maneuvers with 4 groups of electrospray thrusters.

Design and Test of an Embedded Systems Controller for a BiModal CubeSat Propulsion System

2021-12-01 , Manchikanti, Kaushik

The Spectre Propulsion System is an effort to develop a bimodal propulsion system for CubeSats. Spectre aims to use green propellant to both drive a small chemical monopropellant thruster as well as an electrospray system. The project is a collaboration between NASA MSFC, Georgia Tech, and MIT. The propulsion unit hardware and controller are being developed within the GLRG at the SSDL at Georgia Tech, the systems engineering effort is being led by NASA MSFC, and the electrospray system development is being led by MIT SPL As a part of that effort, a low-cost system controller is being developed using commercial-of-the-shelf parts to drive costs down and still be able to withstand the harsh environments of space missions. This paper shows the development and test process of Spectre Propulsion System controller. From the high-level system architecture to the testing of specific hardware, the total controller system development effort will be outlined.

Self-explanation collaborative tool

2021-12 , Elouedrhiri, Driss

One of the main challenges educational institutions face is keeping students engaged during online classes. Self-explanatory techniques show some efficiency in keeping students engaged. But, there are still rooms for improvement to get students more motivated and contribute toward the evolution of system content. This paper summarizes the existing self-explanatory method and presents a designed solution to extend it as a collaborative platform. The tool is an extension plugin that universities and educational platforms can integrate into their existing solutions. This paper defines the tool's integration and how it improves student engagement.

Design of a Payload Avionics Interface Board for the VISORS (VIrtual SuperOptics with Reconfigurable Swarms) CubeSat Mission

2021-12-01 , Kolhof, Maximilian

The following paper details the current state of the Payload Avionics Interface Board (PAIB) design for the VISORS mission. It is also intended as a resource for the students who will continue to develop its design into the future and manufacture the first realizations of this design. Context is provided for the entire VISORS mission as well as the need for this specific subsystem and how it contributes to success of the mission. The motivation and requirements for the PAIB are summarized to define the scope of the subsystem. Electrical and mechanical interfaces for the PAIB are discussed. Detail is provided for design decisions and component selection which has been completed thus far, with some guidance provided to aid in additional component selection. Finally, open action items and risks are discussed to set the stage for the next actions which must be completed to ensure development remains on schedule.

GTatrium for Georgia Tech

2021-12 , Hays, Emily L.

In 2018, The Commission for Creating the Next in Education (CNE) at Georgia Tech took a comprehensive look at what higher education might look like in 2040. The resulting document, “Deliberate Innovation, Lifetime Education,” uses strategic foresight to explore the future of education at Georgia Tech and outlines several initiatives for Georgia Tech to provide a more valuable experience to its stakeholders. One of these initiatives is the GTatrium, a scalable gathering place to real and virtual services for Georgia Tech to achieve a distributed global presence. Like the physical atrium of a building, the atrium is a flexible space located near learners. The GTatrium is designed to provide personalized education, career development, advising, and specialized learning experiences to current Georgia Tech students, and to alumni, prospective learners, and the community at large. This master’s project presentation will discuss the research, service design, and overarching strategy of the GTatrium, and aims to address, “How can Georgia Tech serve learners in their communities throughout their liftetimes?” A research goal was to define the GTatrium experience, identify user groups, core services, a conceptual service model, and draw with broad strokes what this could look like for Georgia Tech in the next decade of its development. The presentation will suggest next steps for the development and implementation of the atrium that can be deployed internationally. This project was undertaken in conjunction with the Center for 21st Century Universities, which will continue with the project after the completion of this master’s project.

Design of a Cold Gas Propulsion System for the SunRISE Mission

2021-08-01 , Skidmore, Logan

NASA’s SunRISE Mission is a formation of six identical 6U CubeSats that will form the first low-frequency space-based radio telescope, studying the radio characteristics of the solar environment in order to yield insights into solar events that affect the safety of Astronauts and spacecraft, as well as systems on Earth. These spacecraft use cold-gas propulsion systems designed by the Space Systems Design Lab to perform delta-V and RCS maneuvers. Utilizing additive manufacturing processes for the main structure and tank, the SunRISE cold-gas propulsion system represents a continued demonstration of the Space Systems Design Lab’s ability to design custom propulsion systems using flight-capable hardware. This report outlines the development of the SunRISE Propulsion System from its initial proposal through its design evolution, concluding in discussion of its future integration and test campaign, as well as the future flight units.
