Abstract

Traditional academic Space Situational Awareness (SSA) research has relied on Consumer Off the Shelf (COTS) systems for collecting metric and lightcurve data. Herein, we present an alternative approach to develop a sensor system for space object characterization. Two 0.6-meter F/4 electro-optical (EO) systems were developed for collecting lightcurve and spectral data. The optomechanical design includes over 200 individual parts and was modeled using SolidWorks. Optical design analysis was performed with raytracing software (ZEMAX). A combinations of test, analysis, inspection, and demonstration procedures verified the components of the design. Methods to complete this project include finite element analysis of mechanical components, optical testing methods (Focault Knife Edge Test and Couder Mask Test), tests to verify the function of the thermometers, and a final pointing model test. The entire cost of the design and fabrication of these two EO systems was significantly lower than a COTS alternative. With careful planning and coordination, the deployment times were also reduced compared to a commercial system. This project shows that development of hardware and software for SSA research could be accomplished in an academic environment.
