A Web-Based Job Management System For Three-Dimensional Printing And Scanning At The University Of North Dakota, Dalyn Limesand, Stephanie Hollman, Jeremy Straub, Scott Kerlin

Jeremy Straub

Three-dimensional (3D) printers have gained popularity for use for many different projects. The work presented herein aims to make this process simpler. This paper discusses a system that will allow individuals from across campus to submit object files for printing by a 3D printer, without having to schedule appointment and manually operate it.

Logistical requirements dictate some level of human involvement, despite a goal of creating a fully automated system. Involvement areas include converting /preparing submitted files, sending the job to the printer, print tray preparation, and completed object removal. From a user’s perspective, however a seamless experience is anticipated. …

Electrical Power System For An Open Hardware Cubesat, Sofiane Chaieb, Michael Wegerson, Jeremy Straub, Ronald Marsh, David Whalen

Jeremy Straub

The OpenOrbiter program is developing a complete set of CubeSat hardware and software to facilitate the development of a 1-U CubeSat (10 cm x 10 cm x 10 cm, 1.33 kg spacecraft) with a parts cost of less than $5,000. This poster covers the electrical power system (EPS) for that spacecraft. The EPS is an assemblage of components that supplies all spacecraft subsystems with power, while performing health assessment of the battery and electrical buses. The EPS has a crucial role in the spacecraft and thus has to be developed and tested with extreme care.

The EPS generates power using …

Development Of A Metal-Printing 3d Printer At The University Of North Dakota, Benjamin Kading, Michaela Kegley, Tiana Delzer, Jeremy Straub, Scott Kerlin

Jeremy Straub

Three-dimensional (3D) printing is being used for numerous applications: from consumer hobbies to the development of aircraft parts. However, inexpensive 3D printers have been constrained in material selection to plastic. These printer use the fused deposition modeling (FDM) method of printing, which is a relatively new technology that utilizes computer numerical control (CNC) techniques to deposit melted material at specific places. Other methods, for example, include laser sintering and stereolithography. With 3D printing, layers are stacked upon each other and via this compilation of layers, a 3D object is formed. Currently there are a variety of materials that can be …

Advancement Of The Software Defined Radio (Sdr) For The Open Orbiter Project, Michael Wegerson, Jeremy Straub, Sima Noghanian, Ronald Marsh

Jeremy Straub

Software Defined Radios (SDRs) are an exciting development in radio technology. The SDR uses software to perform many of the tasks that only hardware could previously complete on a traditional analog radio. Such tasks include encoding/decoding or applying filters to reduce noise on the signal. This powerful fusion of software and hardware have allowed SDR to be smaller in size and have a greater functionality than traditional radio setups; a perfect solution for our Open Orbiter satellite. Currently, the implementation we use consists of a simple $20 USB TV decoder for receiving, a Raspberry Pi micro-computer for transmission, and the …

Enabling Interplanetary Small Spacecraft Science Missions With Model Based Data Analysis, Jeremy Straub

Jeremy Straub

Small spacecraft operating outside of Earth orbit are significantly constrained by the communica- tions link available to them. This is particularly true for stand-alone craft that must rely on their own antenna and transmission systems (for which gain and available power generation are limited by form factor); it is also applicable to ‘hitchhiker’-style missions which may be able to utilize (quite likely very limited amounts of) time on the primary spacecraft’s communications equip- ment for long-haul transmission.

This poster presents the adaptation of the Model-Based Transmission Reduction (MBTR) frame- work’s Model-Based Data Analysis (MBDA) component for use on an interplanetary …

Exposing Multiple User-Specific Data Denominated Products From A Single Small Satellite Data Stream, Atif F. Mohammad,, Emanuel Grant, Jeremy Straub, Ronald Marsh, Scott Kerlin

Jeremy Straub

This paper presents a research work on small satellite data stream and related distribution to associated stakeholders, which is a field that needs to get explored in more detail. The algorithm that is presented to extract USDDP (User-Specific Data Denominated Products) is a self managing body, which will be within as Open Space Box environment or OSBE as a novel idea. It contains an individual stream transmitted by the small satellite, which later is to be converted into USDDP. The context defined here deals with area in detail. Contexts are vitally important because they control, influence and affect everything within …

Open Space Box Model: Service Oriented Architecture Framework For Small Spacecraft Collaboration And Control, Atif F. Mohammad, Jeremy Straub

Jeremy Straub

A Cubesat is a small satellite with very less competence to compute, it requires software engineering techniques, which can enhance the computational power for this small box. A model-driven approach of software engineering, which is called OSBM or Open Space Box Modeling technique, is an excellent solution to this re-source maximization challenge. OSBM facilitates apparition of the key solution pro-cesses computation and satellite related data elements using Service Oriented Ar-chitecture 3.0 (SOA 3.0) as base to work on to design services. The key challenges that can be handled by utilizing OSBM include concurrent operation and tasking of few as five …
