Abstract

The Advanced Land Observing Satellite (ALOS) "Daichi" launched in January 2006 has been operated successfully on orbit for more than 3 years, delivering a huge number of high-resolution images and contributing to a variety of fields that include disaster management support and regional environment monitoring. Consequently, the Japan Aerospace Exploration Agency (JAXA) is planning 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 will produce pan-sharpened images as a base map of the Geographical Information System (GIS) in systematic observation. ALOS-3 will also promptly provide precise images for determining the damage of a disaster-stricken area in an emergency observation because one of the most important missions of ALOS-3 is disaster monitoring. Some observation capabilities are required to be upgraded from ALOS. ALOS has a panchromatic band with 2.5 m resolution. To provide precise observation data, ALOS-3 has been improved to have a high resolution better than 1 m and 50 km or wider swath. JAXA has been conducting the conceptual design and defining the system requirements for the spacecraft and the mission instrument for ALOS-3.
