Optical Sensor Follow-up Tasking on High Priority Uncorrelated Track

2017-02 , Murphy, Timothy S. , Luu, K. Kim , Sabol, Chris , Holzinger, Marcus J..

This work proposes a methodology for tasking of electro-optical sensors to search an area of state space for a particular object. This work enables current space situational awareness programs to more efficiently follow-up on an unknown object. In particular, this work looks at searching for an unknown space object with prior knowledge in the form of a set, which can be defined via an uncorrelated track. The follow-up can occur from a different location at a different time, which often requires searching a large region of the sky. This work analyzes the divergence of a search region to inform a time optimal search method. Simulation work is included to explore the effects of sensor geometry, initial detection uncertainty, and handoff delay time on total time and feasibility of follow-up.
