Design and Implementation for KOMPSAT-5 Orbit Determination Operations

SpaceOps 2012 Conference, 2012
KOrea-Multi-Purpose-SATellite (KOMPSAT)-5 is the first Korean satellite to perform synthetic aperture radar (SAR) mission and support radio occultation. In order to process SAR and radio occultation data, precise position and velocity are required. KOMPSAT-5 orbit determination system consists of Operational orbit determination (OOD) and precise orbit ...

Radio Occultation Mission in Korea Multi-Purpose Satellite KOMPSAT-5

2009
The first occultation mission in the Korean space program, KOMPSAT-5, is scheduled for launch in 2010. KOMPSAT-5 will have a dual frequency GPS receiver to generate precision orbit determination data and occultation data. The KOMPSAT-5 spacecraft and the characteristics of its occultation payload are described in this paper.

Bias Assessment of Nasa Team and ASI Summer SEA ICE Concentrations in the Chukchi SEA using Kompsat-5 SAR

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
Bias assessment of sea ice concentration (SIC) derived from passive microwave sensors is very important because it has been used as an important parameter for climate change research. In this study, we analyzed biases in SICs retrieved from NASA Team (NT) and Arctic Radiation and Turbulence Interaction STudy (ARTIST) Sea Ice (ASI) algorithm implemented

A study of the feasibility of using KOMPSAT-5 SAR data to map sea ice in the Chukchi Sea in late summer

Remote Sensing Letters, 2017
ABSTRACTIn this study, a sea ice mapping model based on Random Forest (RF), a rule-based machine learning approach, has been developed for the Korea Multi-Purpose Satellite-5 (KOMPSAT-5) Synthetic Aperture Radar (SAR) data in Enhanced Wide swath mode obtained from 6 August to 9 September 2015 in the Chukchi Sea.
