ALOS-2 is a follow-on mission from ALOS-1 ("DAICHI"). This satellite was launched on 24 May 2014 with enhanced capabilities.

The state-of-the-art L-band Synthetic aperture Radar aboard ALOS-2 is an active microwave radar using the 1.2 GHz frequency range which will have enhanced performance compared to ALOS/PALSAR. The PALSAR-2 is capable of observing day and night and in all weather conditions.

ALOS-2 will have a spotlight mode (1 to 3m) and a high resolution mode (3m to 10m), whilst PALSAR has a 10m resolution. It will allow comprehensive monitoring of disasters by providing users with more details than its predecessor.
The observation frequency of ALOS-2 will be improved by greatly expanding the observable range of the satellite by up to 3 times through an improvement in observable areas (from 870km to 2,320 km) as well as giving ALOS-2 a right and left looking function.
