Synspective Inc., a provider of Synthetic Aperture Radar (SAR) satellite data and analytics solutions, is pleased to announce that the Japan Aerospace Exploration Agency (JAXA) has selected the company as the data service provider for the Advanced Radar Satellite, Daichi-4 (ALOS-4).
To expand access to SAR data, we are committed to delivering comprehensive analysis and solutions. Building on our experience with Daichi-2 (ALOS-2), we aim to grow satellite data distribution network across Japan and international markets. Together with our SAR satellite, StriX, this initiative will enhance SAR imagery availability for customers and foster new opportunities.
ALOS-4 is JAXA’s satellite launched via the H3 Launch Vehicle No. 3 from the Tanegashima Space Center. Equipped with an advanced L-band synthetic aperture radar, it builds on ALOS-2’s foundation to deliver world-leading resolution and observation coverage.
While both StriX and ALOS-4 employ SAR technology, they offer distinct characteristics. StriX utilizes X-band radar, which provides high-resolution imagery through its short wavelength, interacting with surface features like vegetation. This makes it excellent for detecting structural changes in buildings and roads, delivering detailed ground surface information beneficial for urban infrastructure and rapid disaster assessment.
ALOS-4 operates in the L-band, which has a longer wavelength that performs well even through vegetation. This makes it ideal for forested regions and grasslands. These attributes also make ALOS-4 advantageous for long-term monitoring of ground deformation and embankments.
