Instrument | Status/ Accuracy | Instrument Description | Measurement Technology | Timeline |
AGRI Advanced Geosynchronous Radiation Imager | Operational
| A multiple channel radiation imager, one of the primary instruments aboard FY-4. Technically featured by a precisely designed two-mirror structure, capable of accurate and flexible sensing in two dimensions, and minute-level fast sector scanning. Frequent Earth imaging over 14 bands with off-axis three reflections of the primary optic system. On-board black body available for IR calibrations at very short time intervals. | n/a |  |
C-Band SAR C-Band Synthetic Aperture Radar | Operational
| Marine core services, land monitoring and emergency services. Monitoring sea ice zones and arctic environment. Surveillance of marine environment, monitoring land surface motion risks, mapping of land surfaces (forest, water and soil, agriculture), mapping in support of humanitarian aid in crisis situations. | n/a |  |
