Design And Implementation Of Satellite Software To Facilitate Future Cubesat Development, Timothy Whitney, Jeremy Straub, Ronald Marsh

Jeremy Straub

The OpenOrbiter project is a campus-wide effort at the University of North Dakota to design and build a low-cost CubeSat-class satellite. The intent is to create a publically- available framework that allows a spacecraft to be built with a parts cost of less than USD $5,000 (excluding mission payload-specific costs). This paper focuses on OpenOrbiter’s software system methodology and implementation.

Current work seeks to create a generalized framework that other CubeSat developers can use directly or alter to suit their mission needs. It discusses OpenOrbiter’s overall design goals with an emphasis on software design. The software architecture is divided into …

Course Outcome Prediction Using An Expert System, Michael Kuehn, Jared Estad, Jeremy Straub, Eunjin Kim

Jeremy Straub

Determining how well a student will perform in a course based on their prior knowledge of the course material and other factors may help determine student placement and the need for remedial instruction. This poster presents work on the creation of an expert system that attempts to predict a student’s performance based on a pre-evaluation test and responses to background preparation questions. This work utilizes data from prior students to train and test the system.

Classroom Polling Software For Use With Mobile And Web-Based Devices, Nick Renford, Jeremy Straub, Scott Kerlin

Jeremy Straub

The goal of this project is to create an interface for Android, iOS, and Win-dows Phone smartphones, as well as a web interface that will act as a “clicker”. The instructors will be able to send out questions, and the students will be able to answer the questions, and get feedback if the instructor wants them to have it. The teacher can decide whether the feedback is instant or manually initiated, and what format the response will be, whether it includes the correct answer, and what type of chart, if any, indicating the most com-monly selected answer(s). There will be …

A Raspberry Pi-Based 3d Scanner, Cam Peterson, Pann Ajjimaporn, Jiaoni Wang, Jeremy Straub, Scott Kerlin

Jeremy Straub

This poster presents work on building a 3d scanner. A 3d scanner is a device that analyzes a real-world object to collect data on its shape and or appearance. The collected data can then be used to construct digital 3d models. The scanner is made up of 50 Raspberry Pi computer boards and cameras. We will construct 12 arms each holding four cameras per arm. The purpose of this is to be able to scan anything and produce a 3d model that we then would be able to send to the 3d printer or use in a video game or …

The Use Of The Roofsat For Computer Science And Engineering Education, Jeremy Straub, Ronald Marsh

Jeremy Straub

This poster presents an overview of a tool that has been created to provide students with real-world experience in the design, development and operation of control and scientific mission software for a cyber-physical system. The ROOFSAT, developed at UND, is a low-cost analog for a small spacecraft (though in many ways these capabilities also enable similar UAV work). The ROOFSAT was constructed with approximately $1,500 generously provided by the John D. Odegard School of Aerospace Sciences out of commercially-available parts. It includes multiple cameras, a pan-tilt mount and the same space-qualified computer hardware which has been used on both spacecraft …

The International Trafficking In Arms Regulations: Precluding Innovation In Academic Spacecraft Engineering — Or Are They?, Jeremy Straub, Joe Vacek

Jeremy Straub

Government regulations and uncertainty about their enforcement can be a significant barrier to innovation. In business, it is undesirable to consume time and other resources developing a product that cannot be sold or which requires navigating significant bureaucracy for each sale. In academ-ia, where limited funding is available prior to the submission of a grant pro-posal and receipt of an award, proposal-stage compliance costs can derail a project long before it begins. This paper reviews the International Traffick-ing in Arms Regulations (ITAR) and their impact on spacecraft research in academia, private research labs and industry. It reviews the exemptions available, …

Formalizing Mission Analysis And Design Techniques For High Altitude Ballooning, Jeremy Straub, Ronald Fevig

Jeremy Straub

High altitude balloon (HAB) missions can be and are used to teach concepts related to spacecraft and satellite design. A HAB mission, however, presents unique characteristics, which must be understood and respected to produce a desirable outcome. Because of this, flying an unaltered satellite design as a HAB payload would be as undesirable as utilizing an unaltered HAB design as a satellite. A well-defined process for HAB mission design is thus needed. The process presented mirrors commonly used space mission design processes to facilitate easy transition between the two. It is also comparatively simple, due to the smaller scale of …
