HUANJING-1A/1B (HJ-1A/1B) was launched on 6 September 2008, HJ-1A is an optical satellite with a multispectral (MS) camera and a hyper spectral (HIS) camera. HJ-1B is also an optical satellite with a multispectral camera and a IRMSSInfrared multispectral camera on board.

Its overall objective is to establish an operational Earth observing system for disaster monitoring and mitigation and to improve the efficiency of disaster mitigation and relief. And it mainly applies in the fields such as environmental monitoring and prediction, solid waste monitoring, disaster monitoring and prediction. HJ is the abbreviation for "Huan Jing" - meaning "environment".
