Abstract Beyond catalog maintenance, a sun-synchronous sensor can provide valuable information about GEO objects’ characteristics. Algorithms were designed for attitude anomaly detection of GEO satellites and spin axis determination for tumbling objects using space-based non-resolved optical data. The spin axis orientation of a tumbling GEO object can be estimated by analyzing its observed tumble rate variations with an orbiting sensor. Simulated space-based observations using a GEO satellite model, with variable spin rates and axial tilt angles, have suggested that the algorithms are effective at estimating a GEO satellite’s spin rates and orientation.
