Abstract : Modern space situational awareness is focused on the detection, tracking, identification, and characterization of passive and active resident space objects. In the past, this process relied primarily on ground-based sensors. However, difficulties arise when smaller, more distant, or otherwise dim objects are considered. Space based sensors may help alleviate some of these difficulties. The work funded under this award has focused primarily on optimal design for a constellation of space based sensors to support the goals of space situational awareness. To that end, the work leverages concepts from computer graphics to analyze sensor coverage strictly from a numerical perspective, enabling a unique design approach that is adaptable to any sensor network for situational awareness applications.
