The Canadian Space Agency (CSA), in collaboration with other Canadian government departments, has carried out activities and initiated early phase studies for a Canadian Hyperspectral Mission.The goal of the mission is to provide a new and powerful space-based tool for delivering frequently updated hyperspectral remote sensing information products for a broad range of operational users in governments and industries worldwide. This mission is intended to launch a constellation of three microsatellites, each of which will observe the Earth with 3 times finer footprint on the ground and 8 times wider ground coverage than those of the current and upcoming hyperspectral missions in the world. This will position Canada as a world lead in this area. To achieve this ambitious goal CSA has been working with Canadian industry teams to develop innovative technologies. Two different concepts of low-mass high-performance hyperspectral imaging systems have been proposed and studied. A novel linear variable optical filter based hyperspectral payload approach has been investigated. The feasibility studies showed that both concepts can accommodate to a microsatellite and are feasible. In this seminar, Dr. Qian will briefly introduce the principle of satellite hyperspectral imaging systems, their current status and main applications in Earth observation. Then he will present the innovative technology developed in Canada for tackling the technical challenges in designing and building such a high-end spacecraft payload.
