- Abstract
- Conjunction assessment and collision avoidance of the Communications Ocean and Meteorological Satellite (COMS) in Geostationary Earth Orbit (GEO) were investigated. An abandoned inclined geosynchronous orbit satellite was approached to COMS. Backward and forward orbit propagation based on the Conjunction Summary Message (CSM) from Joint Space Operations Center (JSpOC) was carried out. COMS satellite orbit change due to the stationkeeping maneuver and momentum dumping operation was considered to generate Owner/Operator ephemeris. Differences of orbital position in radial, along-track, and cross-track were analyzed for conjunction assessment. In this case, regular East-West station-keeping maneuver and North-South station-keeping maneuver act like collision avoidance maneuvers for along-track and cross-track separation.
