Scheduling For A Small Satellite For Remote Sensed Data Collection, Donovan Torgerson, Christoffer Korvalnd, Jeremy Straub, Ronald Marsh

Jeremy Straub

Small satellites, such as CubeSats, serve as excellent platforms for the collection of data that can be supplied to a geographic information system. To serve this need, they require a robust and lightweight task scheduler due to their limited onboard power production capabilities as well as internal space restrictions. Because of these constraints, schedules must be optimized; however, the scheduling optimization process must be performed using limited processing (CPU) power.

Several considerations must be taken into account in order to make a scheduler for these systems. This poster highlights requirements such as inter-dependency of onboard systems, and limited windows of …

Testing And Integration Team Project Management, Tyler Leben, Jeremy Straub, Scott Kerlin

Jeremy Straub

The Testing and Integration Team plays an integral role in the development of the open source CubeSat known as Open Orbiter. Like any project, the Testing Team’s project can benefit from structure and management to effectively utilize it’s time and resources. CSCI 297 teaches the skills needed to turn a good idea into successful endeavor. By applying skills such as effective planning, setting milestones, dealing with changes and supervising to an actual project, Open Orbiter has transformed from a pipe dream to a real, obtainable goal. Doing this has turned learning about project management into more that just power points …

Openorbiter Payload Software, Tim Whitney, Kyle Goehner, Jeremy Straub, Scott Kerlin

Jeremy Straub

The Payload Software team is responsible for developing the image processing and task decomposition systems on the Open Orbiter satellite1. The image processing software performs operations to enhance the quality of the images collected by the onboard camera, specifically, mosaicking, which takes multiple images and stitches them together to make a larger image and super resolution, which takes multiple low resolution images of the same area to produce a higher resolution image2,3,4. The task decomposition part of the system decomposes tasks defined by the user into jobs that then get sent to the operating system to be performed. This system …

OpenOrbiter is producing a 1-U CubeSat spacecraft1 to facilitate the construction of low-cost2 spacecraft by others in the future. The Operating Software team is in charge of designing and creating the software that controls most of the CubeSat’s operations such as image capturing, storage management, and temperature sensing. The project management deliverables that we have worked on as a team are the Project Definition, Work Breakdown Structure, and the Project Schedule. The Project Definition defines exactly what our project team will be developing including, but not limited to, what the team is in charge of developing, what its not in …

Ground Station Software Team Project Management, Zach Maguire, Marshall Mattingly, Christoffer Korvald, Jeremy Straub, Scott Kerlin

Jeremy Straub

In CSCI 297 class we partake in learning the roles of software team leads and developers. With hands on activities that get us involved in what a real manager of a software team may do such as: defining a project, planning a project, developing a work breakdown structure, estimating the work, developing a project schedule, etc. This work is performed in the context of the OpenOrbiter project which seeks to build a low-cost spacecraft1 that can be produced with a parts budget of approxi-mately $5,0002 by schools worldwide. The ground station software team’s purpose within Open Orbiter project is to …

Software For Openorbiter, Christoffer Korvald, Jeremy Straub, Scott Kerlin, Ronald Marsh

Jeremy Straub

The software development effort for the OpenOrbiter project consists of four teams: operating software development, payload software development, ground station software development and testing. These teams are designing and developing the software required to create a turn-key spacecraft design1 which can be produced at a price point of under USD $5,000 by faculty, students and researchers world-wide2. Through this process, students are gaining valuable real-world experience3,4 in areas of indicated interest5. Each team is headed by a team lead who is responsible for conducting weekly meetings and organizing the activities of the team. During the Fall, 2013 semester, team leads …

A Review Of Online Collaboration Tools Used By The Und Openorbiter Program, Jeremy Straub, Christoffer Korvald

Jeremy Straub

The OpenOrbiter program at the University of North Dakota is a student-initiated, student-run effort to design, develop, test, launch and operate a CubeSat-class spacecraft to validate the designs of the Open Prototype for Educational NanoSatellites (a framework that will be made publically-available to allow faster and lower-cost missions at other educational institutions worldwide). OpenOrbiter involves (at various participation levels) over 200 faculty and students spanning five colleges and ten departments. To coordinate this large group of participants who comprise over seventeen teams and work at disjoint hours in a plethora of locations, online project management, software source control and hardware …

Payload Processing Aboard An Open Source Software Cubesat, Jon Sand, Kyle Goehner, Christoffer Korvald, Josh Berk, Jeremy Straub

Jeremy Straub

The Open Prototype for Educational NanoSats (OPEN) is a system that focuses on reducing spacecraft mission costs. It provides a set of designs that is freely available to anyone online. The OpenOrbiter CubeSat provides designs to create a small satellite using economical materials available allowing a parts budget of under $5,000. One aspect of this design is CubeSat payload processing software. This is the process of taking a single image, or multiple images taken at the same time, and manipulate them. This manipulation an include compression, mosaicing, super resolution, or any combination thereof. The first step in this process is …

Model-Based Software Engineering For An Imaging Cubesat And Its Extrapolation To Other Missions, Atif Mohammad, Jeremy Straub, Christoffer Korvald, Emanuel Grant

Jeremy Straub

Small satellites with their limited computational capabilities require that software engineering techniques promote efficient use of spacecraft resources. A model-driven approach to software engineering is an excellent solution to this resource maximization challenge as it facilitates visualization of the key solution processes and data elements.

The software engineering process utilized for the OpenOrbiter spacecraft, which is a remote sensing technology demonstrator, is presented. Key challenges presented by the Open Orbiter project included concurrent operation and tasking of five computer-on-module (COM) units and a flight computer and the associated data marshaling between local and general storage. The payload processing system (consisting …

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 …

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, …
