ALOS (Advanced Land Observation Satellite) was launched on January 24, 2006 from Tanegashima Space Center, Japan. JAXA Japan Aerospace Exploration Agency owns the satellite. ALOS was set into sun-synchronous orbit at the height of 691.65 km. ALOS is fitted with PRISM cartographic stereo camera acquiring imagery with resolution of up to 2.5 m, AVNIR-2 multispectral camera acquiring color imagery with resolution of 10 m, as well as L-diapason radar (PALSAR*) intended for 24-hour all-weather Earth survey and acquiring imagery of resolution from 10 to 100 m. ALOS satellite imagery applications: creation and refreshing of topographical maps and special plans up to 1:25000 scale, environmental survey of the petroleum and other minerals sites, topographical background survey, agricultural fields assessing etc. Basic characteristics: | Mode: | PRISM(Panchromatic) | AVNIR-2(Multispectral)) | PALSAR (radar) | | Spectral bands (mkm): | 0,52-0,77 | blue: 0.42-0.50 green: 0.52-0.60 red: 0.61-0.69 near IR: 0.76-0.89 | L-diapason radar | | Spatial resolution: | 2.5 m (at nadir) | 10 m (at nadir) | 7 m — 100 m | | Data transmission rate: | 960 Mbits/sec | 160 Mbits/sec | 240 Mbits/sec | | Swatch Width: | 35 km (at nadir) | 70 km (at nadir) | 70 km – 350 km | | Radiometric resolution: | 8 bits per pixel | 8 bits per pixel | 5 bits per pixel | | Revisit time: | 46 days | 46 days | 46 days | | Stereo imagery: | Available from a single pass | n/a | n/a |
