Advanced Land Observing Satellite 4 (ALOS-4), also called Daichi 4 (daichi is a Japanese word meaning "great land"), is a 3,000 kg (6,600 lb) Japanese L-band synthetic-aperture radar (SAR) satellite that was launched on July 1, 2024.
Only 52 of 4,300 images of Japan could be updated based on data from ALOS. [4] [5] Then, JAXA announced the problem was solved. [6] ALOS was used to analyze several disaster sites. [7] [8] [9] Images of the devastated Japanese coast following the 2011 Tōhoku earthquake and tsunami were among the last major contributions from ALOS. [10] [11]
ALOS-3 carried OPS (OPtical Sensor), a multi-band optical camera which is an upgrade from the PRISM sensor. [2] OPS was capable of observing a 70-kilometer (43 mi) wide strip of land on Earth. [5] In addition to the RGB and infrared band covered by the predecessor ALOS satellite, ALOS-3 has two additional bandwidths: coastal and red edge.
The satellite contains a 1.2 GHz synthetic-aperture radar (SAR) sensor that is intended to be used for cartography, monitoring of naval traffic and disaster monitoring of Asia and the Pacific. [3] JAXA initially hoped to be able to launch the successor to ALOS during 2011, but these plans were delayed until 2014 because of budget restrictions.

Changed from the originally manifested ALOS-4 due to the launch failure of H3-TF1 / ALOS-3. First successful flight of the H3 launch vehicle. Separation of VEP-4 was performed after the deorbit burn of the second stage. 17 February 12:05 [44] GSLV Mk II: F14: Satish Dhawan SLP: ISRO: INSAT-3DS [45] ISRO: Geosynchronous: Meteorology: In orbit ...
But in 2015, the ALOS PALSAR data became unrestricted, [28] and the Sentinel-1 data is also unrestricted. [19] In June 2013, the Alaska Satellite Facility released newly processed, 35-year-old data [29] from the 1978 Seasat satellite mission. [30] Before this release, only 20 percent of the Seasat SAR data had been processed digitally. [31]
ALOS-4 (Daichi 4) JAXA: Low Earth Earth observation: In orbit: Operational First Operational flight of H3 rocket. ALOS-4 (Daichi 4) will replace the ALOS-2 (Daichi 2) satellite, which was launched in 2014. 3 July 08:55 [3] Falcon 9 Block 5: Starlink Group 8-9 Cape Canaveral SLC-40: SpaceX: Starlink × 20 SpaceX: Low Earth: Communications: In ...
