Abstract

This study investigates abrupt orbital changes, i.e. orbital anomalies (OAs), of the very old upper-stages Titan Transtages inserted into the geostationary orbit (GEO) region in 1960s and 1970s to find evidences of breakups. The product of the radiation pressure coefficient (Cr) and the area-to-mass ratio (A/m) are estimated by utilizing eccentricity histories of target objects separated into before-OA phase and after-OA phase. To find evidences of breakups, characteristics of likelihood distributions of CrA/m are compared between before-OAs and after-OAs. The known breakup of the Transtage 1968-081E is utilized as the reference of the comparison study.
