1	Optical Astrometry and Orbit Determination Patrick Michael Kelly (8817071) 08 May 2020 (has links) The resident space object population in the near-Earth vicinity has steadily increased since the dawn of the space age. This population is expected to increase drastically in the near future as the realization of proposed mega-constellations is already underway. The resultant congestion in near-Earth space necessitates the availability of more complete and more accurate satellite tracking information to ensure the continued sustainable use of this environment. This work sets out to create an operational system for the delivery of accurate satellite tracking information by means of optical observation. The state estimates resulting from observation series conducted on a GPS satellite and a geostationary satellite are presented and compared to existing catalog information. The satellite state estimate produced by the system is shown to outperform existing two-line element results. Additionally, the statistical information provided by the processing pipeline is evaluated and found to be representative of the best information available for the satellites true state.

2	Novel Analysis Framework Using Quantum Optomechanical Readouts For Direct Detection Of Dark Matter Ashwin Nagarajan (10702782) 06 May 2021 (has links) With the increase in speculation about the nature of our universe, there has been a growing need to find the truth about Dark Matter. Recent research shows that the Planck-Mass range could be a well-motivated space to probe for the detection of Dark Matter through gravitational coupling. This thesis dives into the possibility of doing the same in two parts. The first part lays out the analysis framework that would sense such an interaction, while the second part outlines a prototype experiment that when scaled up using quantum optomechanical sensors would serve as the skeleton to perform the analysis with.
