GEO-KOMPSAT 2B (etnews.com)

On March 6th, Geostationary Korea Multi-Purpose Satellite 2B (GEO-KOMPSAT 2B), also known as Chollian 2B, successfully entered orbit. The satellite will carry out a precise correction process to optimize the quality of data until the full-blown service, which will launch in October. The Communication, Ocean and Meteorological Satellite (COMS), also known as Chollian, the first weather observation geostationary satellite developed with South Korean technology, launched in June 2010. GEO-KOMPSAT 2B is a follow-up satellite to the COMS. From October, it will take over the mission of observing the oceans and environment, and from next year, it will watch air environments and monitor such things as fine dust. In GEO-KOMPSAT 2B, hyper-spectral technology is used. It can figure out the concentration of air pollutants by detecting the amount of light that is absorbed by air pollutants. Also, while conventional satellites travel at an altitude of 700 to 1,000 km, GEO-KOMPSAT 2B travels at 35,786km altitude, which enables GEO-KOMPSAT 2B to observe all of East Asia, ranging from Japan, Northern Indonesia, and Southern Mongolia. Through GEO-KOMPSAT 2B, the Korean government will be able to gather the basic data to trace the source of fine dust and prepare for international air-environmental conflicts.
