The Advanced Land Observing Satellite (ALOS) "Daichi," launched in January 2006, has been operating successfully on orbit for four and a half years. In that time it has delivered a very large number of high-resolution images and has contributed to making basic maps, updating maps, gathering information on natural resources, and disaster management support in a variety of fields. The Japan Aerospace Exploration Agency (JAXA) has been planning a satellite system for the ALOS follow-on program. The ALOS follow-on program consists of two satellites: one is a radar satellite called ALOS-2, the other is an optical satellite called ALOS-3. ALOS-3 carries an optical imager with more enhanced capabilities than those of the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) aboard ALOS. ALOS-3 will produce a precise basic map with its systematic observation to be used in the Geographical Information System (GIS). ALOS-3 will also promptly provide precise postdisaster images to detect damaged areas through emergency observations when disasters occur. JAXA has been defining system requirements for the spacecraft and the mission instrument of ALOS-3, as well as conducting the conceptual design. This paper introduces the latest design, the mission concept, and the current status of ALOS-3.
