Daqi 1 [SAST]
Daqi 1 (DQ 1) is Chinese atmospheric environment monitoring satellite.
Daqi-1 is equipped with five remote sensing instruments including atmospheric detection lidar, high-precision polarization scanner, multi-angle polarization imager, ultraviolet hyperspectral atmospheric composition detector and wide-field imaging spectrometer, which can greatly improve global carbon monitoring and atmospheric pollution monitoring ability. The satellite is similar to Gaofen 5 and is based on the SAST-5000B bus.
The instruments are:
- ACDL (Aerosol and Carbon dioxide Detection Lidar)
- DPC-II (Directional Polarimetric Camera)
- EMI-II (Environmental Trace Gas Monitoring Instrument)
- POSP (Particulate Observing Scanning Polarization)
- WSI (Wide Spectral Imager)
