The Advanced Land Observing Satellite-2 (ALOS-2) was successfully launched on 24th May 2014. The mission sensor of ALOS-2 is the Phased Array type L-band Synthetic Aperture Radar-2 called PALSAR-2 which is the state of the art L-band SAR system. Until now after the successful completion of initial checkout after launching, ALOS-2 has been contributed to a lot of emergency observations for natural disasters, not only in Japan but also in the world. Furthermore, based on the Basic Observation Scenario (BOS) of ALOS-2, 10m global map data and other mode data are routinely collected and archived. This paper describes the results of ALOS-2 operation in nominal operation phase and outline of future ALOS series missions, especially ALOS-4 launched JFY2021.
Shin-ichi Sobue got a master degree of engineering from Toyohashi university of Technology in Japan in 1989 and got a philosophical doctor of engineering from Kennedy-Western University in USA in 2000. His major is image data analysis of earth observation data. He joined JAXA in 1989 and had been work for earth observation satellite ground system development and data research management. From January 2017, he serves Advanced Land Observing Satellite-2 (ALOS-2) project manager of directorate I of space technology in JAXA.
