Analysis of Collision Avoidance Maneuver Frequency for the KOMPSAT-2 and the KOMPSAT-5 [PDF]
Journal of the Korean Society for Aeronautical & Space Sciences, 2011 In this paper, a collision avoidance maneuver frequency for the KOMPSAT-2 and the KOMPSAT-5 is analyzed. For the statistical prediction of the avoidance maneuver frequency, mission orbits, responsive time, accepted collision probabilities, and positional uncertainties of primary and secondary objects are considered. In addition, the collision avoidance

Development of Mobile Active Transponder for KOMPSAT-5 SAR Image Calibration and Validation [PDF]
The Journal of Korean Institute of Electromagnetic Engineering and Science, 2013 KOMPSAT-5(KOrea Multi-Purpose SATellite-5) has a benefit of continuously conducting its mission in all weather and even night by loading SAR(Synthetic Aperture Radar) payload, which is different from optical sensor of KOMPSAT-2 satellite. During IOT(In-Orbit Test) periods, SAR image calibration should be conducted through ground target of which ...
