ISM S-band CubeSat Radio Designed for the PolySat System Board
<p>Cal Poly’s PolySat CubeSat satellites have begun to conduct more complex and scientifically significant experiments. The large data products generated by these missions demonstrate the necessity for higher data rate communication than currently provided by the PolySat UHF radio. This thesis …

Fault Tolerant and Flexible CubeSat Software Architecture
… been educational in nature. Cal Poly's project, PolySat, has gained significant experience from the launch of five CubeSats and has designed an entirely new hardware platform based on the knowledge gained from these missions. This hardware is a significant upgrade from what the previous missions …

A CubeSAT Orbital Test Platform for an Electrothermal Plasma Micro-Thruster
… of the California Polytechnic State University's PolySat Team. This thesis will baseline the use of Pocket Rocket, an electrothermal plasma micro-thruster, originally developed by the Australian National University. The thruster has seen continued development with the PolySat team, and the PolySat …

Design of an Integrated Acceleration Acquisition Subsystem to Satisfy High-Speed and Low-Area Requirements for CubeSats
<p>Cal Poly San Luis Obispo’s PolySat team is designing the Multipurpose Orbital Spring Ejection System (MOSES) in order to record acceleration data during the launch of CubeSats as well as to provide GPS coordinates to locate the position of CubeSats once they are injected into orbit. This work …

Reliable Software Updates for On-Orbit CubeSat Satellites
… The CubeSat development team at Cal Poly, PolySat, has recently redefined its standard avionics platform to support more complex mission capabilities with this robustness in mind. A significant addition was the integration of the Linux operating system, which provides the flexibility to …

Hardware-in-the-Loop Simulation for Verification of CubeSat Attitude Determination and Control Subsystem
… a hardware-in-the-loop simulation based off of PolySat's software architecture that allows for a higher granularity of ADCS testing than standard unit tests do. A space environment model is simulated, and virtual sensors and actuators are created to interface the simulation with an actual ADCS …

A Data-Driven Approach to Cubesat Health Monitoring
… system for CubeSat missions developed by the PolySat lab. This system is integrated into PolySat's flight software and provides real time health monitoring of the spacecraft during its mission. Any anomalies detected are reported and further analysis can be done to determine the cause. The …

Development of Tools Needed for Radiation Analysis of a Cubesat Deployer Using Oltaris
<p>Currently, the CubeSat spacecraft is predominantly used for missions at Low- Earth Orbit (LEO). There are various limitations to expanding past that range, one of the major ones being the lack of sufficient radiation shielding on the Poly-Picosatellite Orbital Deployer (P-POD). The P-POD …

Nanosatellite Launch Data-Logger (Sync)
<p>CubeSat designers are increasingly looking to incorporate delicate structures and optics into their payloads. These delicate payloads, however, may not survive the required absolute-worst-case launch vibration testing needed for flight certification. To help address this problem, and to better …
