Openorbiter: Analysis Of A Student-Run Space Program, Jeremy Straub Sep 2013

Openorbiter: Analysis Of A Student-Run Space Program, Jeremy Straub

Jeremy Straub

Students at the University of North Dakota, as part of faculty-mentored teams in a student-lead program, are working to broaden participation in humanity's exploration of space. The OpenOrbiter Small Spacecraft Development Initiative (OSSDI) is demonstrating two complementary paradigm-changers. First, the initiative facilitates student involvement in all aspects of a space program, without the preconceptions present in established space activities. Second, it is demonstrating a low-cost framework for small spacecraft development. These combined activities are poised to demonstrate a new way forward for space exploration: combined, they allow risk-taking exuberance and a cost of entry that makes risk-taking exuberance acceptable, even …


Open Beyond Orbit: Using The Designs From The Open Prototype For Educational Nanosats Outside Of Earth Orbit, Jeremy Straub Jun 2013

Open Beyond Orbit: Using The Designs From The Open Prototype For Educational Nanosats Outside Of Earth Orbit, Jeremy Straub

Jeremy Straub

This paper presents an overview of the Open Prototype for Educational NanoSats (OPEN) and its prospective use in interplanetary missions. OPEN is framework to facilitate the low-cost creation of CubeSat-class spacecraft via using publically available (provided by the OPEN project) de- signs, software, fabrication instructions and test plans. The base open configuration is designed to be able to be produced with a parts budget of under $5,000. Despite this low cost, it is a very ro- bust spacecraft (with capabilities meeting or exceeding many of the vendor-kit solutions which cost eight-or-more times this amount).

Two approaches for using the OPEN …

Open And Openorbiter: A Needs-Responsive Solution For The Small Satellite Community, Jeremy Straub, Atif Mohammad

Jeremy Straub

The Open Prototype for Educational NanoSats (OPEN) is an initiative launched at the University of North Dakota, as a public service to the nation and the world. The OPEN team is working to create a design, set of implementation instructions and a testing plan for a 1-U CubeSat (which can also serve as a basis for a 2-U or 3-U CubeSat with limited modifications). These will be made publically available to facilitate the low-cost implementation of CubeSat programs at other institutions. The target of the designs is to allow fabrication with a parts budget of approximately $5,000. This is, thus, …

Work To-Date On Mechanical Design For An Open Hardware Spacecraft, Jacob Brewer, Brian Badders, Josh Berk, Jeremy Straub

Jeremy Straub

The OpenOrbiter CubeSat seeks to demonstrate the designs created for the Open Prototype for Educational NanoSats (OPEN) initiative. OPEN provides a set of freely available design documents that can be utilized by educational and research teams worldwide. The OPEN structure implements a different strategy than most other CubeSats, allowing it to maximize the use of the overhang space (an area of space between the supports for the frame rails and the wall in the PPOD deployer). It also provides a location for payload components or a propellant tank at the spacecraft’s center of mass. This design is enabled by a …


An Expert System For Spacecraft Design, Jeremy Straub, Christoffer Korvald, Tyler Hill, Joshua Berk Apr 2013

An Expert System For Spacecraft Design, Jeremy Straub, Christoffer Korvald, Tyler Hill, Joshua Berk

Jeremy Straub

Designing a spacecraft is a complicated process that can be problem-prone. This is particularly true in the case of a small spacecraft where volume and mass limitations are enforced by form factor requirements. The Open Prototype for Educational NanoSats implements several restrictions beyond those from the CubeSat form factor, including two different board size specifications which impact the configuration of the payload area support structure and the size of available batteries.

OpenEdge aims to avoid the discovery of form factor, OPEN-specific and other configuration issues during final assembly by checking prospective configurations against the applicable requirements and constraints set during …

Sensor And Computing Resource Management For A Small Satellite, Abhilasha Bhatia, Kyle Goehner, John Sand, Jeremy Straub, Atif Mohammad, Christoffer Korvald

Jeremy Straub

A small satellite in a low-Earth orbit (e.g., approximately a 300 to 400 km altitude) has an orbital velocity in the range of 8.5 km/s and completes an orbit approximately every 90 minutes. For a satellite with minimal attitude control, this presents a significant challenge in obtaining multiple images of a target region. Presuming an inclination in the range of 50 to 65 degrees, a limited number of opportunities to image a given target or communicate with a given ground station are available, over the course of a 24-hour period. For imaging needs (where solar illumination is required), the number …
