The Japanese earth observing satellite program consists of two satellite series: those mainly for atmospheric and marine observation, and the ones mainly for land observation. The Advanced Land Observing Satellite(ALOS) is the satellite that follows JERS-1 and ADEOS and enhances their land observing technology. ALOS will be used for cartography, regional observation, disaster monitoring, and resource surveying.
ALOS is one of the world's largest earth observation satellites whose function is to collect global and high resolutional land observation data. Because of the large increase of observation data it will be transmitted to EOC via both DRTS and as a direct downlink. In this way observation data can be rapidly acquired by EOC from all areas.
