- Korea-MultiPurpose-SATellite-2 (KOMPSAT-2) has been successfully operated by Mission Control Element (MCE) since the launch of July 28, 2006. The spacecraft was built by Korea Aerospace Research Institute (KARI) and the MCE system was developed by Electronics and Telecommunications Research Institute (ETRI). This paper presents status of the operational and precise KOMPSAT-2 Orbit Determination (OD) in Mission Analysis and Planning System (MAPS), one of MCE subsystems. The KOMPSAT-2 is the first satellite to perform Precise Orbit Determination (POD) using single frequency GPS data to process high resolution image data obtained from Low Earth Orbiter (LEO) satellite in Korea. Operational Orbit Determination (OOD) using GPS navigation solution data should satisfy 10 m Root-Sum-Square (RSS) in one sigma and Precise Orbit Determination (POD) is required to fulfill 1 m RSS in one sigma. In order to demonstrate the accuracy of the KOMPSAT-2 OD, OOD was compared with POD and POD was tested using orbit overlapping solution. The orbit accuracy of OOD and POD results met the given requirement, within 5-6 m RSS to the reference data and 60-75 cm RSS in orbit overlapping solution, respectively. © 2010 by the American Institute of Aeronautics and Astronautics, Inc.
