Advanced Land Observation Satellite

<- ALOS

ALOS-3 ->

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.[3]

## Launch

[edit]

ALOS-2 was launched from Tanegashima, Japan, on 24 May 2014 by a H-IIA rocket.[4]

## Mission

[edit]

The satellite contains a 1.2 GHz synthetic-aperture radar (SAR) sensor that is intended to be used for cartography, monitoring of naval traffic and disaster monitoring of Asia and the Pacific.[3] JAXA initially hoped to be able to launch the successor to ALOS during 2011, but these plans were delayed until 2014 because of budget restrictions.
