KOMPSAT-2 Precise Orbit Determination Using GPS Data
25th AIAA International Communications Satellite Systems Conference (organized by APSCC), 2007A Precise Orbit Determination (POD) has been developed for Korea multipurpose satellite-2 (KOMPSAT-2) to fulfill the requirement for 1 m positioning accuracy. The POD is resolved using single-frequency Global Positioning System (GPS) data in a dynamic filter.

Precise geometric modeling for KOMPSAT-1 satellite imagery
IEEE International Geoscience and Remote Sensing Symposium, 2003The geometric modeling for 3-D positioning was performed using the strip stereo images with the ancillary data of KOMPSAT-1. As a result, the satellite position vector offset was corrected by only one ground control point and the accuracy for the geometric modeling improved to 25.7 m RMSE.

Soil moisture detection using KOMPSAT-5 SAR data
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010The applicability of the KOMPSAT-5 (Korea Multi-Purpose Satellite-5) SAR on soil moisture detection is addressed in this paper. At first, the penetration into and reflection from bare soil surfaces at X-band are compared with those at L-band for homogeneous and inhomogeneous moisture profiles.

Long-Term Evolution of the KOMPSAT-1 Orbit
The Journal of the Astronautical Sciences, 2005A long-term orbital evolution of the Korea Multi-Purpose Satellite-1 is monitored and analyzed in this paper. Four years of orbital evolution is divided into four phases in terms of the operational status of the satellite. Orbit determination results, which are obtained from the satellite’s GPS navigation data, are used to convert the osculating orbit ...
