A Two-Phase Development And Validation Plan For North Dakota's First Spacecraft, Jeremy Straub, Ronald Marsh
A Two-Phase Development And Validation Plan For North Dakota's First Spacecraft, Jeremy Straub, Ronald Marsh
Jeremy Straub
The Open Prototype for Educational NanoSats (OPEN) aims to make space more accessible for educational and other uses by driving down the cost of CubeSat development. This paper presents a tentative plan for the use of two orbital missions as part of a two-phase technology demonstration sequence focusing on raising the technology readiness level (TRL) of OPEN to a level suitable for wide use and adoption. It presents an overview of a two-mission development plan including mission objectives, requirements and constraints. The paper considers how the phase one mission’s spacecraft may serve as a lower-cost platform for some users in …

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.

The OpenOrbiter Small Spacecraft De-velopment Initiative seeks to create a low-cost, easy-to-assemble CubeSat1 design that can be produced with a parts budget of under USD$5,0002. In [1], an initial design was presented; this design was enhanced in [3] and has been revised further. The current design, which has switched focus from defining specifications, requirements and constraints to identifying real parts which meet these previously defined constraints, is presented herein.

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 …
