ALOS-1 Satellite Capabilities
High-Resolution Earth Observation with Optical and SAR Imaging
The Advanced Land Observing Satellite-1 (ALOS-1), launched by the Japan Aerospace Exploration Agency in 2006, was designed to deliver high-resolution Earth observation through both optical and synthetic aperture radar (SAR) sensors. With flexible imaging modes and wide-area coverage, ALOS-1 supported diverse applications from 3D terrain modelling to disaster monitoring.
Its instruments, including the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM), enabled precise topographic mapping and detailed land analysis. ALOS-1 played a crucial role in environmental monitoring, forestry management, and natural disaster response through frequent, reliable, and high-quality image data acquisition.
Although ALOS-1 has completed its mission, its contributions remain foundational to Earth science, land use planning, and satellite imaging advancements globally.
Comprehensive Monitoring
Supported monitoring of land use, coasts, forests, and disaster-prone regions for environmental and conservation planning.
Wide Swath Imaging
Captured large areas in single passes, ideal for applications like agriculture, forestry, and change detection.
Flexible Imaging
High-resolution spotlight mode with left/right look angles enabled 3D mapping and terrain elevation modelling.
Key Features and Benefits of ALOS-1
- Dual-sensor system with optical and SAR capabilities for multi-application imaging.
- Wide swath width allowed efficient monitoring of large and remote areas.
- Generated 3D topographic maps via PRISM sensor, supporting geological and elevation analysis.
- Crucial asset in disaster response efforts after earthquakes, floods and landslides.
- Supported deforestation tracking, land use change studies, and biodiversity monitoring.
- Provided data for global research in glaciology, oceanography, and land cover analysis.
