Ballistic Coefficient Estimation for Reentry Prediction of Rocket Bodies in Eccentric Orbits Based on TLE Data

Figure 1

BC estimates and BC from from TLE data (a, b) and the mean perigee radius according to TLEs (c, d) for object 28452 in the 180 days before reentry. In (a, c) the TLEs have been filtered on mean motion only and in (b, d) on mean motion and perigee radius.
