Advanced Land Observing Satellite (ALOS), also called Daichi (a Japanese word meaning "land"), was a 3810 kg Japanese satellite launched in 2006. After five years of service, the satellite lost power and ceased communication with Earth, but remains in orbit.
Although the predecessor ALOS satellite had featured 2 optical cameras in addition to L-band (1.2 GHz/25 cm) radar, ALOS-2 had optical cameras removed to simplify construction and reduce costs. The PALSAR-2 radar is a significant upgrade of the PALSAR radar, allowing higher-resolution (1 x 3 m per pixel) spotlight modes in addition to the 10 m ...
The AVNIR was a multispectral radiometer for observing the Earth in the visible and near-IR wavelengths at high spatial resolution. The AVNIR employs a Schmidt optical system and an electronic scanning CCD silicon array. The AVNIR consisted of three visible channels (0.40-0.50, 0.52-0.62, 0.62-0.72 microns) and one near-IR channel (0.82-0.92 ...

ALOS-4 is further enhanced from ALOS-2 by equipping the new PALSAR-3 synthetic aperture radar, which employs the new digital beamforming SAR technology. While the observation range in spotlight mode with a resolution of 1 m x 3 m was 25 km square for ALOS-2, ALOS-4 enables observation over a 35 km square area.
Preview the page, and if something doesn't look right, chances are there's a problem. While the printed books will differ from the PDF version, they share a lot of similarities. If something looks weird in the PDF version, chances are it will also look weird in the printed book. Usually there are three kinds of problems:
Completion of IKONOS-2 construction was projected for July 1999 with a January 2000 launch. [12] In reaction to the loss of IKONOS-1, the spacecraft was renamed IKONOS [ 12 ] [ 13 ] and its processing accelerated, resulting in a launch on 24 September 1999 at 18:22 UTC, also from Vandenberg aboard an Athena II rocket.
