Abstract

A classification of ambiguous spacecraft relative orbits in sequential orbit estimation is formulated based on the use of linear dynamics with continuous range-only measurements. Using relative orbit elements the ambiguous orbits are categorized into two cases: mirror orbits, which conserve the size and shape but transform the orientation of the true relative orbit, and deformed orbits, which both distort the shape and change the orientation. Furthermore, it is shown that the inclusion of nonlinearities in the filter model can help resist the tendency of an extended Kalman filter to converge to the ambiguous orbits.
