Advanced Land Observing Satellite (ALOS) is a Japanese high-resolution Earth observation satellite planned for launch in 2004. The planned imaging sensors are Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM), Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2), and Phased Array type L-band Synthetic Aperture Radar (PALSAR). The AVNIR-2 swath width will be 70 km for the VNIR channels and 35 km for the panchromatic channel, and consists of three sensors pointed fore, nadir, and aft and has cross-track pointability +/-40 degrees. PALSAR is an L-band SAR and also has a 70 km swath width and a 20- to 55-degree incidence angle.
