Advanced Land Observing Satellite-2 (ALOS-2), also called Daichi-2, is a 2,120 kg (4,670 lb) 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 Camera (CIRC) will provide supplementary data about sea-going ships and provide early warnings of missile launches.
