Space situational awareness (SSA) techniques must be developed to provide adequate understanding of the space environment. Optical techniques provide one mechanism to achieve this capability. Using a linear polarimeter mounted to a 16-inch telescope, the polarimetric signature of different satellites across different seasons was collected. These signatures reveal the degree of linear polarization (DOLP) and angle of linear polarization (AOLP) of the light reflected from observed satellites. Two features of geosynchronous satellite polarization signatures can be observed: a quadratic baseline originating from solar panels, and a polarization glint originating from the bus and payload. In demonstrating physical significance behind a satellite’s polarization signature, these findings suggest satellite polarization may provide utility in identification and characterization of space objects.
