Design And Testing Of A Nanosatellite Simulator Reaction Wheel Attitude Control System, Fredric William Long
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Attitude control of a satellite is required for the pointing of communications antennas and other instruments. For this reason, a control algorithm capable of precision pointing is important. Because the process of sending a satellite into space is time consuming and costly, ground-based methods of testing are paramount. A simulator is a low-cost, groundbased system made to mimic the conditions of a weightless satellite in space. The simulator used in this project controls attitude through applying torque to reaction wheels. The objective of this project is to derive and test a control algorithm for the attitude control of a satellite …

Retrofitting Two Solar Hot Water Systems For Year Round Operation, Zachary A. Cook
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Solar energy in a variety of applications is again becoming more widely used. Solar collectors have been installed during the construction of two Utah State University buildings: Wetlands Discovery located in Kaysville, Utah and Swaner Nature Preserve located in Park City, Utah. While these systems are capable of capturing a significant amount of solar energy, problems have been encountered when the demand is less than the system’s capacity. This project report documents the problems encountered while operating the two solar water heating systems and how the systems were modified to be operational year round under typical operating conditions. The peak …
