Several optical monitoring strategies by a ground-based telescope to protect a Geostationary Earth Orbit (GEO) satellite\udfrom collisions with close approaching objects were investigated. Geostationary Transfer Orbit (GTO) objects, Inclined\udGeoSynchronous Orbit (IGSO) objects, and drifted GEO objects forced by natural perturbations are hazardous to\udoperational GEO satellites regarding issues related to close approaches. The status of these objects was analyzed on the\udbasis of their orbital characteristics in Two-Line Element (TLE) data from the Joint Space Operation Center (JSpOC).\udWe confirmed the conjunction probability with all catalogued objects for the domestic operational GEO satellite,\udCommunication, Ocean and Meteorological Satellite (COMS) using the Conjunction Analysis Tools by Analytical Graphics,\udInc (AGI). The longitudinal drift rates of GeoSynchronous Orbit (GSO) objects were calculated, with an analytic method and\udthey were confirmed using the Systems Tool Kit by AGI. The required monitoring area was determined from the expected\uddrift duration and inclination of the simulated target. The optical monitoring strategy for the target area was analyzed\udthrough the orbit determination accuracy. For this purpose, the close approach of Russian satellite Raduga 1-7 to Korean\udCOMS in 2011 was selected
