ALOS Satellite Sensor
ALOS was one of the world's largest earth observation satellites whose function is to collect global and high resolution land observation data. ALOS data was made available at conditions similar to those of ERS and Envisat missions, namely for scientific 'Category-1' use as well as commercial applications.

ALOS Satellite Sensor (2.5m)
ALOS (Advanced Land Observation Satellite) has been decommissioned. ALOS was successfully launched on January 24, 2006 from the Tanegashima Space Center.

The ALOS (renamed "Daichi") satellite sensor had three remote-sensing instruments: the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) and for digital elevation models (). The Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) for precise land coverage observation, and the Phased Array type L-band Synthetic Aperture Radar (PALSAR) for day-and-night and all-weather land observation and enabled precise land coverage observation and can collect enough data by itself for mapping on a scale of 25,000:1, without relying on points of reference on the ground. Some of its objectives where cartography, , natural resource surveys and technology development.
In April 2011, the satellite was found to have switched itself into power-saving mode due to deterioration of its solar arrays. Technicians could no longer confirm that any power was being generated. It was suggested that metiorides may have struck ALOS, creating the anomaly which eventually led to its shutdown.
On 12 May 2011, JAXA sent a command to the satellite to power down its batteries and declared it dead in orbit.
The ALOS AVNIR-2 and PRISM Imagery and PALSAR data is available from the exiting archives.
ALOS New Launches
On Saturday 24 May 2014 an H-IIA rocket orbiting the second Advanced Land Observation Satellite, Daichi-2 – better known as ALOS-2. Liftoff from the iconic Tanegashima Space Centre was on schedule at 12:05 local time (03:05 UTC). ALOS-2 will continue the L-band SAR observations of the ALOS PALSAR (Phased Array L-band Synthetic Aperture Radar) and will expand data utilization by enhancing its performance.
The ALOS-3 Satellite sensor is scheduled to be launched during 2015 and will carry the optical sensor called PRISM-2 which succeeds to the ALOS/PRISM mission with enhanced performance in high resolution (0.8 m), wide swath (50 km) and high geo-location accuracy. PRISM-2 will acquire stereo pair images with two telescopes for stereo mapping and produce precise Digital Surface Models (DSM) and Digital Elevation Models (DEM). It is also considered to carry Hyper-spectral Imager Suite (HISUI), which is developed by the Ministry of Economy, Trade and Industry (METI) of Japan. JAXA has conducted the phase-A study on ALOS-3 spacecraft and mission instruments, with prototype testing of key components.

Rapid Acquisition/Rush Tasking
Rush tasking orders for satellite image data around the world are accepted in support of live events, natural disasters, global security, and various other applications in which FAST delivery of image data is critical. In most instances, we can provide image data within 24 hours after the initial data has been acquired and delivered via FTP and DVD media. A Spanish version is also available at http://www.satimagingcorp.es.
