Software Design For An Intelligent Attitude Determination And Control System, Matthew Russell, Jeremy Straub

Jeremy Straub

Space exploration and satellite missions often carry equipment that must be accurately pointed towards distant targets, therefore making an effective attitude determination and control system (ADCS) a vital component of almost every spacecraft. However, the effectiveness of the ADCS could decrease drastically if components shift during launch, degrade in efficiency over the course of the mission, or simply fail. Prior work [0] has presented a concept for a adaptive ADCS which can respond to changing spacecraft conditions and environmental factors. This poster presents an implementation for a lazy learning ADCS is presented that uses past maneuver data to construct and …

Testing A Novel Cryptosystem For Use In Securing Small Satellite Communications, Samuel Jackson, Scott Kerlin, Jeremy Straub

Jeremy Straub

Cryptography in the domain of Small Satellites is a topic of growing importance. While large satellites are likely to have the hardware requirements to run common cryptographic algorithms, small satellites are extremely limited in both hardware capabilities, which limits the speed and security of cryptosystems implemented in software, and available physical space, which limits the ability to include cryptosystems implemented in hardware. However, small satellites are growing in popularity, and as such securing communications becomes a necessity for some. The Department of Defense is exploring the possibility of using CubeSats, a type of small satellite, in their operations, as are …

The Development Of A Nanosatellite-Class Sunsat At The University Of North Dakota, Corey Bergsrud, Jeremy Straub, Robert Bernaciak, Subin Shahukhal, Benjamin Kading, Karl Williams, Hossein Salehfar, Johnathan Mcclure, James Casler, David Whalen, Elizabeth Becker, Sima Noghanian

Jeremy Straub

This poster presents the details of work on the SunSat spacecraft design initiative at the University of North Dakota. This project seeks to advance technologies1 and to increase public awareness of Space Solar Power based via visualization, science and engineering work. It will also focus on the development and demonstration of a workable solution and consider the economic benefits2 that the proposed (and alternate) solutions may generate. This poster details the design project which will construct a transmitting Nano Space Solar Power Satellite (NSSPS) and a power reception satellite for a space-to-space Microwave Wireless Power (MWP) demonstration. The SmallSatstyle spacecraft4, …

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 …

Openorbiter Combined Software Work Breakdown Structure, Jeremy Straub, Timothy Whitney, Tyler Leben, Kelton Karboviak, Zach Maguire, Christoffer Korvald, Scott Kerlin

Jeremy Straub

As part of CSCI 297, students created work breakdown structures for different areas of the OpenOrbiter project’s software groups. In CSCI 207, they learned about all aspects of project management via experiential learning. They acted as project management ‘consultants’ to the OpenOrbiter software teams. To facilitate the creation of the work breakdown structures, they interviewed team leads, attended team meetings and discussed current progress and needs with members of the teams. In some cases, they collected additional information from reference sources and/or spoke with other teams which would be the ‘customer’ of a particular area of the software system. These …

Work On A Software Defined Radio (Sdr) For A Cubesat-Class Spacecraft, Michael Wegerson, Jeremy Straub, Sima Noghanian

Jeremy Straub

A Software Defined Radio (SDR) will be used for OpenOrbit-er satellite to ground communications. The use of SDR al-lows for a smaller, more versatile radio then what a stand-ard hardware radio can provide; perfect for the unpredicta-ble environment Open Orbiter will be exposed to. Current implementation uses a simple $20 USB TV decoder for the receiver and the open-source program GNU Radio for soft-ware decoding. Broadband FM transmissions have been re-ceived and decoded successfully and on-going experimen-tation for receiving satellite communications are yielding promising results.

Business Case For A Constellation Of 6u Solar Powered Cubesats In Leo, Corey Bergsrud, Jeremy Straub, Matthew Clausing, Johnathan Mcclure, James Casler, Sima Noghanian

Jeremy Straub

This paper presents a business case for launching a constellation of 6U Solar Power CubeSats (SPCS) to low-Earth orbit (LEO) to provide power to other spacecraft. This approach may prove economically feasible as a business endeavor, as it allows power to be transmitted in a high-density manner via microwave frequencies reducing the collection surface area required on the consumer spacecraft significantly and reducing the requirement for energy storage.

Several 6U SPCS units can target their energy streams to form a swath of energy to provide an increased aggregate level of power transfer to a particular craft as it flies though …

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 …
