Orbit determination processing of two-line element (TLE) sets to extract additional orbital accuracy has been studied for several years. Various approaches have claimed success, and full catalog processing is conducted at ESA. We extend the existing analyses and conduct detailed evaluations of alternatives for the OD processing. This includes examination of the number of TLEs used, method of splicing ephemerides, force models, fit spans, satellite category, and if the satellite is classified as maneuverable.
