Jeremy Straub

The OpenOrbiter Small Spacecraft Development Initiative at the University of North Dakota [1] aims to make ac-cess to space for research and educational purposes easier by enabling the creation of low-cost CubeSats. It is creating the Open Prototype for Educational Nanosats (OPEN), a framework for developing a 1-U CubeSat space-craft with a parts cost of less than $5,000 [2]. The designs [3], documentation and computer code from this will be made publically available to enable the development of programs at other institutions.

The OpenOrbiter Small Satellite Development Initiative at the University of North Dakota [1] is working make space research and education more accessible world-wide [2], through the design and public release of a complete set of plans, software and other documents (see [3]) for a 1-U CubeSat. This design targets a parts cost of no more than $5,000 [4]. These lowered costs, combined with the efficiencies of the CubeSat form fac-tor [5] and free-to-qualified-developer launch services [6, 7] should facilitate greater access to space for the ed-ucational, research and other communities.

The OpenOrbiter Program aims to develop a tem-plate for a CubeSat spacecraft that can be used world-wide to reduce spacecraft development costs1. Unlike other approaches, which may require $50,000 in upfront hardware costs2 or $250,000 in design expenses2, an OPEN-class spacecraft can be built with a parts budget of under $5,0003. This aims to enable low-cost educa-tional missions and missions in developing regions4.

Scheduling Algorithm Development For An Open Source Software Spacecraft, Calvin Bina, Jeremy Straub, Ronald Marsh

Jeremy Straub

The OpenOrbiter project at the University of North Dakota is working to develop a set of designs for a CubeSat class spacecraft as well as a working, modular collection of open source code that can be used by other CubeSat projects as a starting point for development. The availability of these designs and this codebase should foster accelerated development for other CubeSat projects, allowing those projects to focus their effort on their own application area, instead of reinventing the proverbial wheel. One aspect of this is to implement a task scheduler which will run on a Raspberry Pi flight computer …

Development in support of these objectives is ongoing with work focusing on the completion of the development of a stable system. This poster presents an overview of current work on the project and …

Scheduling For A Small Satellite For Remote Sensed Data Collection, Donovan Torgerson, Christoffer Korvalnd, Jeremy Straub, Ronald Marsh

Jeremy Straub

Small satellites, such as CubeSats, serve as excellent platforms for the collection of data that can be supplied to a geographic information system. To serve this need, they require a robust and lightweight task scheduler due to their limited onboard power production capabilities as well as internal space restrictions. Because of these constraints, schedules must be optimized; however, the scheduling optimization process must be performed using limited processing (CPU) power.

Several considerations must be taken into account in order to make a scheduler for these systems. This poster highlights requirements such as inter-dependency of onboard systems, and limited windows of …

Roofsat: Teaching Students Skills For Software Development For Gis Data Collection And Other Activities, Jeremy Straub, Ronald Marsh, Donovan Torgerson, Christoffer Korvald

Jeremy Straub

Small Spacecraft provide an excellent platform for the collection of geospatial data. In order to enable the low-cost creation of small remote sensing space-craft in a university environment, a training pathway for students is required. The Realistic Operational Ob-ject for Facilitating Software Assessment and Testing (RoofSat) serves to provide students with experience developing software for a small satellite platform typi-cal of those used for remote sensing missions. It al-lows software to be tested with hardware that re-sponds in a similar manner to that found on the satel-lite for a fraction of the cost of development. This poster details the goals …

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 …
