As development of CubeSat based architectures increase, methods of deploying constellations of CubeSats are required to increase functionality of future systems. Given their low cost and quickly increasing launch opportunities, large numbers of CubeSats can easily be developed and deployed in orbit. However, as secondary payloads, CubeSats are severely limited in their options for deployment into appropriate constellation geometries. This thesis examines the current methods for deploying cubes and proposes new and efficient geometries using secondary launch opportunities. Due to the current deployment hardware architecture, only the use of different launch opportunities, deployment direction, and deployment timing for individual cubes in a single launch are explored. The deployed constellations are examined for equal separation of Cubes in a single plane and effectiveness of ground coverage of two regions. The regions examined are a large near-equatorial zone and a medium sized high latitude, high population density zone. Results indicate that simple deployment strategies can be utilized to provide significant CubeSat dispersion to create efficient constellation geometries. The same deployment strategies can be used to develop a multitude of differently dispersed constellations. Different launch opportunities can be utilized to tailor a constellation for a specific region or mission objective. Constellations can also be augmented using multiple launch opportunities to optimize a constellation towards a specific mission or region. The tools developed to obtain these results can also be used to perform specific analysis on any region in order to optimize future constellations for other applications. v ACKNOWLEDGEMENTS There is a significant amount of people that I want to thank for their continuous help in my long path to completing this work. First, I would like to thank my advisor Dr. Jordi Puig-Suari for helping me define and shape what was an initially vague idea regarding constellations into my completed thesis. I also want to thank Justin Foley and Roland Coelho at CubeSat for their perpetual help and patience. As I progressed through my work and continuously needed new, and at times, odd information they quickly and promptly worked with me to find a solution. I want to thank Dr. Kira Abercromby for assisting and advising me whenever possible while my primary advisor was on sabbatical. Her help in the early formation of my thesis allowed me to develop the concepts required for this research. (STK) software versions 9 and 10.
