There is a strong need for accurate resident space object (RSO) state estimates. For radar RSO measurements, these estimates are initiated by Gibbs and Herrick-Gibbs algorithms. Presently, there is no clear distinction on when to switch between these two methods. In this paper, we present a statistical comparison between Gibbs and Herrick-Gibbs, taking into account measurement error via Monte Carlo. The overall trend of the performances of the methods is consistent with what is expected. However, the results also show that Herrick-Gibbs can remain the more accurate method for much larger track length arclengths than is suggested in the literature.
