This thesis presents the characterization process of an imaging device for a satellite. The camera system was built by the Space Dynamics Laboratory (SDL) and will be used in the Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) instrument for National Aeronautics and Space Administration's (NASA) Ionospheric Con- nection Explorer (ICON) satellite. This mission will further scientists' understanding of the connection between the Earth's weather and ionospheric conditions. The ionosphere, a part of the atmosphere, interferes with satellite communications, causing disturbances and disruptions. By learning more about the ionosphere through the data collected by this instrument, scientists will better understand its effects on our communications.
