Summary
ALOS (DAICHI) is an Earth Observation and Radar satellite launched by JAXA on January 24, 2006, from Tanegashima Space Center using the H-IIA 2022 launch vehicle. The spacecraft measures 6.5 meters in length with a diameter of 4.5 meters and a span of 28 meters. It has a dry mass of 3800 kg and was designed to operate for 3 years, with plans for up to 5 years. ALOS is equipped with PALSAR (Phased Array-type L-band Synthetic Aperture Radar), PRISM (Panchromatic Remote-sensing Instrument for Stereo Mapping), and AVNIR-2 (Advanced Visible and Near-Infrared Radiometer type 2). It uses a deployable solar array generating approximately 4 kW at the end of life, along with batteries. The satellite's shape is described as a box with two panels and has an RCS value of 13.593. ALOS was manufactured by TSUK/NECTF for JAXA to conduct Earth Observation missions.
