摘要

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.rnALOS-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 post-disaster images to detect damaged areas through emergency observations when disasters occur.rnJAXA has been defining system requirements for the spacecraft and the mission instrument of ALOS-3, as well as conducting the conceptual design.rnThis paper introduces the latest design, the mission concept, and the current status of ALOS-3.
