| Abstract: | Situational awareness of Earth-orbiting particles is important for human extraterrestrial activities. Given an optical observation,
an admissible region can be defined over the topocentric range/range-rate space, with each point representing a possible orbit
for the object. However, based on our understanding of Earth orbiting objects, we expect that certain orbits in that distribution,
such as circular or zero-inclination orbits, would be more likely than others. In this research, we present an analytical
approach for describing the existence of such special orbits for a given observation pass, and investigate topological features
of the range/range-rate space by means of singularities in orbital elements. |
