Thermal infrared imaging from geostationary satellite can provide all time, real time and video observation, and it can achieve fast pointing and information acquisition of any object on the earth disk. It is more suitable for timely information acquisition of emergent event such as natural disaster. The paper introduces the development and related applications of GEO thermal infrared imaging technologies during the past several decades. It then introduces a concept of all time, real time and video observation from GEO using two thermal infrared staring imagers with different spatial resolution and field of view (FOV). The low spatial resolution and wide FOV thermal infrared staring imager is used to monitor objects within a large area concerned, while the high spatial resolution and narrow FOV thermal infrared staring imager is used to acquire detailed information of the interesting objects within a small area. The main characteristics and technical solutions about the proposed concept are described in the paper.
