Optical Short-Arc Association Hypothesis Gating via Angle-Rate Information Academic Article uri icon


  • Copyright 2014 by Kohei Fujimoto and K. Terry Alfriend. Given a short-arc optical observation with estimated angle rates, the admissible region is a compact region in the range/range-rate space defined such that all likely and relevant orbits are contained within it. An alternative boundary value problem formulation has recently been proposed where range/range hypotheses are generated with two angle measurements from two tracks as input. In this paper, angle-rate information is reintroduced as a means to eliminate hypotheses by bounding their constants of motion before a more computationally costly Lambert solver or differential correction algorithm is run.
