Estimating the visibility of Sunlight reflected by the holographic retro-reflector of Cubesat Alpha, and to convert this to star apparent magnitude to learn more about the visibility of these sails through reflected sunlight, to in turn determine if glints of these holograms are visible by terrestrial observers.
Software Design For An Intelligent Attitude Determination And Control System, Matthew Russell, Jeremy Straub
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 …
Evolution Of The Software Defined Radio (Sdr) For The Open Orbiter Project, Michael Wegerson, Jeremy Straub, Sima Noghanian
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 …

Store And Forward Routing For Sparse Pico-Satellite Sensor Networks With Data-Mules, Trevor Joseph Koritza
Master's Theses
Satellites are playing an increasingly important role in collecting scientific information, providing communication services, and revolutionizing navigation. Until recently satellites were large and very expensive, creating a high barrier to entry that only large corporations and government agencies could overcome. In the past few years the CubeSat project at California Polytechnic University in San Luis Obispo (Cal Poly) has worked to refine the design and launching of small, lightweight, and less expensive satellites called pico-satellites, opening space up to a wider audience. Now that Cal Poly has the launch logistics and hardware under control, a new problem has arisen. These …

Development Of A Cubesat Pico-Satellite, Phillip Anderson, Jan Sojka
Posters
The CubeSat Project was developed by California Polytechnic State University (CalPoly) and Stanford University in order to provide launch opportunities to universities previously unable to afford access to space. Today, it provides low-cost launch opportunities to students, government, and businesses. The CubeSat program is able to provide these low-cost launch opportunities by defining a common form factor and design guidelines. All satellites conforming to the regulations are able to be deployed from a standard, flight-proven deployment system called a PPOD. By adhering to the prescribed form factor and safety requirements, necessary documents and export licenses are more easily obtained. CalPoly …
