Sign in to saveAlso known as Advanced Land Observing Satellite-2, Daichi-2
Advanced Land Observing Satellite-2 (ALOS-2), also called Daichi-2, is a Japanese satellite launched in 2014. Although the predecessor ALOS satellite had featured 2 optical cameras in addition to L-band (1.2 GHz/25 cm) radar, ALOS-2 had optical cameras removed to simplify construction and reduce costs. The PALSAR-2 radar is a significant upgrade of the PALSAR radar, allowing higher-resolution (1 x 3 m per pixel) spotlight modes in addition to the 10 m resolution survey mode inherited from the ALOS spacecraft. Also, the SPAISE2 automatic ship identification system and the Compact Infra Red

Also, the SPAISE2 automatic ship identification system and the Compact Infra Red Camera (CIRC) will provide supplementary data about sea-going ships and provide early warnings of missile launches.
== Launch == ALOS-2 was launched from Tanegashima, Japan, on 24 May 2014 by a H-IIA rocket.
