Features and Benefits
- Multi-Sensor Synergy: The constellation's unique combination of optical, hyperspectral, infrared, and SAR sensors allows for comprehensive, multi-layered environmental analysis.
- All-Weather Monitoring: With the HJ-1C SAR satellite, data collection is guaranteed for disaster response and environmental monitoring, even in cloudy or rainy conditions.
- Wide Area Coverage: The optical and infrared sensors feature very wide swaths (up to 720 km), making them highly efficient for regional-scale monitoring and rapid assessment.
- Advanced Spectral Data: HJ-1A's hyperspectral imager, with 115 bands, provides detailed data for material classification, while HJ-1B's infrared camera is key for thermal analysis and fire detection.
