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 …

The Creation Of A Communication Systems For A Small Satellite At The University Of North Dakota, Michael Hlas, Jeremy Straub, Ronald Marsh

Jeremy Straub

Software defined radios (SDRs) are poised to significantly enhance the future of small spacecraft communications. They allow signal processing to be performed on a computer by software rather than requiring dedicated hardware. The SDR takes data from the flight computer and converts it into an analog signal that is transmitted via the spacecraft antenna. Because the signal processing is done in software, the radio can be easily reconfigured.

Data is prepared for transmission by TCP stack software onboard the OpenOrbiter Spacecraft and placed in a queue while the spacecraft is listening for a signal from a ground station. When a …

Development Of A Ground Station For The Openorbiter Spacecraft, Jacob Huhn, Alexander Lewis, Christoffer Korvald, Jeremy Straub, Scott Kerlin

Jeremy Straub

The OpenOrbiter Small Spacecraft Development Initiative[1] at the University of North Dakota is working to design and build a low cost[2] and open-hardware / opensource software CubeSat[3]. The Ground Station is the user interface for operators of the satellite. The ground station software must manage spacecraft communications, track its orbital location , manage task assignment, provide security and retrieve the data from the spacecraft. This will be presented via a graphical user interface that allows a user to easily perform these tasks.

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

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 …

This poster provides an update regarding software development work for the OpenOrbiter project. The software development effort for the OpenOrbiter project currently consists of four teams: payload software development, operating software development, ground station software development and testing. The teams are designing and developing the software needed to create and operate a small spacecraft which can be produced for under USD $5,000 by students, faculty and others around the world. Participating students are gaining valuable real-world experience through the process of designing and developing the spacecraft. Each team is headed by a team lead that is responsible for conducting weekly …

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 …

Project Management For The Openorbiter Operating Software Team, Kelton Karboviak, Dayln Limesand, Michael Hlas, Eric Berg, Christoffer Korvald, Jeremy Straub, Ronald Marsh, Scott Kerlin

Jeremy Straub

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 …

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 …
