29 September 2017Overview of the Japanese Advanced Optical Satellite: mission objectives, a satellite system, and an onboard imager
The Japanese Advanced Optical Satellite (called “ALOS-3”) is a successor of the optical mission of the Advanced Land
Observing Satellite (ALOS) “DAICHI” (2006-2011). The main objectives of the ALOS-3 project are to take images of
the global land area with high GSD (<1 m) and wide swath (>70 km), and build a large image database to prepare for
disasters, etc. By extracting the difference before and after the disaster, the situation of the damage would be grasped
quickly. ALOS-3 also contribute to maintenance and update of the geospatial information of all over the world. The
satellite has capabilities to take stereo images, thus the Digital Surface Model (DSM) of the interested area would also be
provided. The data which will be acquired by ALOS-3 is expected to be useful in various social needs. ALOS-3 is
scheduled to be launch in FY2020.
