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 …
