  Building and maintaining a catalog of resident space objects involves several
tasks, ranging from observations to data analysis. Once acquired, the knowledge
of a space object needs to be updated following a dedicated observing schedule.
Dynamics mismodeling and unknown maneuvers can alter the catalog's accuracy,
resulting in uncorrelated observations originating from the same object.
Starting from two independent orbits, this work presents a novel approach to
detect and estimate maneuvers of resident space objects, which allows for
correlation recovery. The estimation is performed with successive convex
optimization without a-priori assumption on the thrust arcs structure and
thrust direction.
